Chances are, we are now seeing more choosing beggars on the Internet than, possibly, ever. With the pandemic and changing consumer habits, the second-hand market is booming. In Spain, for example, 60 percent of people admitted they favor buying used products and giving them a second life. This includes clothes, furniture, and any other products that can be reused, recycled, and upcycled.

In the European country, star products last year were clearly linked to the new situation we find ourselves in, with the sale of second-hand computer monitors, office chairs and desks, exercise bikes and consoles seeing a 23 percent rise in sales.

Furthermore, experts estimate that the second-hand market (especially clothing) will continue to grow in the upcoming years as well. Resale is expected to overtake the traditional thrift and donation segment by 2024.

"For all the challenges Covid posed to our assumptions about consumer behavior, one thing is clear: consumers everywhere are prioritizing value and accelerating the shift to thrift," Anthony S. Marino, president at thredUp, an online consignment and thrift store where people can buy and sell high-quality secondhand clothes, said.

"When times get uncertain, we all focus on our family balance sheet. Brands whose core proposition delivers value and convenience have the opportunity to gain share. Amazon, off-price, and resale are emerging as winners."

However, if you aren't afraid of encountering a few choosing beggars and are willing to sell some of your stuff online, there are plenty of options you can choose from. 

As Stephen Layton and Laura McMullen pointed out on NerdWallet, the major players are Amazon and eBay. But they also have higher fees. On the plus side, they're also some of the most highly-trafficked sites on the Internet. So if speed of sale is your goal, these sites are the way to go. 

You can sell pretty much anything on Amazon, although listing your items in some specialized categories requires Amazon approval and an upgraded selling plan. The company charges several kinds of fees on items sold, depending on what kind of selling plan you have.

If you opt for the standard Individual selling plan, for example, you'll pay Amazon 99 cents per item sold and a referral fee. The referral fee is a percentage of the item's total sale price, including shipping costs but not taxes, and usually ranges from 8% to 20%.

Keep in mind that if you're selling media items, including books, movies, and video games, you pay a $1.80 closing fee, as well.

The upgraded Professional selling plan requires a $39.99 monthly subscription fee, but if you get it you don't have to pay 99 cents per item as you do with the Individual plan. The professional plan makes sense only if you plan to sell more than 40 items per month.

eBay lets you auction and sell a wide range of goods and has a simpler fee structure than Amazon. For most items, you pay eBay 10% of the final sale price of the item, which includes shipping costs but not taxes. If you post more than 50 items in one month, eBay starts charging you 30 cents per listing over 50.

eBay also allows you to promote your listing in various ways for extra fees. For example, you might want to set a reserve price so that your item is auctioned off for at least that minimum amount. For most product categories, the fee to set a reserve price is $5 or 7.5% of the reserve price — whichever is greater, with a maximum fee of $250. eBay charges this fee whether or not your item sells.

Bonanza offers people to sell a range of products similar to Amazon and eBay. It charges fees based on the sale price of the item, plus any amount of the shipping cost over $10. So if you sold an item for $20 and shipped it for $13, your fee would be $23. Bonanza charges you 3.5% of this price; in our example, you’d pay about 80 cents. There's a minimum fee of 50 cents per item.

For items that sell for $500 or more, you pay 3.5% on the first $500 and then 1.5% of the amount over $500.

Bonanza also offers to advertise your listing across the web in exchange for a higher percentage fee.

For local sales, consider Craigslist, Facebook Marketplace, and Letgo. These websites and apps don't always take a cut of your sales, but you’re responsible for connecting with your buyer, meeting up in person, and making the exchange. This is definitely a different style than the online auctions and sales. If you're not comfortable handling all the logistics yourself and then meeting up with a stranger, you might want to skip these.

But if you are, you can arrange to meet your buyer in a public place (many local police stations offer a "safe haven" for such sales) or have a friend hang around while you make the sale. The simplicity here is the key: no packing, shipping, or fees, just cash in your hand. However, unlike many online-only sales sites, these marketplaces don't have any guarantees or protections if your buyer turns out to be a flake.

These bigger online sites are good for getting rid of miscellaneous stuff, but for specialty items, like antiques and vintage clothes, you might want to sell where you could reach a more intentional audience.

Poshmark, for example, is perfect if you want to list men's, women's, and children's clothing, as well as a few other goods. Its fee structure is simple: For all sales under $15, they'll charge you a $2.95 fee; for anything $15 or more, the fee is 20%. Poshmark charges your buyer $7.11 for expedited shipping, so you just print out a prepaid shipping label, box up your clothing and send it off.

There's also Ruby Lane. To post up to 50 items on it, you'll have to pay a $54 monthly maintenance fee. List more than that, and tack on anywhere from a penny to 30 cents per item. Ruby Lane also charges a service fee of 6.7% of the total purchase.

You'll want to have a good idea that you can recoup these maintenance and service fees on Ruby Lane before proceeding.

If you're looking for a way to sell your handmade arts and crafts or vintage collectibles, Etsy is best. You pay 20 cents to list an item and then a 5% transaction fee on the sale price of the item, not including shipping. If you use Etsy Payments to process your payment, you'll be charged an additional 3% plus 25 cents.

But remember, if you put ads in any of these websites/apps and encounter someone as unreasonable as the people we featured in this list, screenshot the conversation and submit it to r/ChoosingBeggars. It would be a crime not to.
