Webstore
Webstore is distinct from the competitors in that it is totally funded by donations, which means there are no extra fees. Unusually, it also enables users to purchase some products without creating an account - however, this is at the discretion of the vendor. This seamless mixture of great qualities makes Webstore a popular choice for individuals selling uncommon or rare products, and it's definitely endearing in its eccentricity.
However, this also implies that you have little recourse if there is a problem. Support is limited and only available through email (or postal mail! ), and there is no settlement center for disputes between sellers and buyers. Also, the website is rather poorly designed by current standards, yet it is functional.
That may seem like a lot of downsides, but you will be amazed at how many odd and rare items you can discover here. Hence, Webstore is a more appealing option than you may anticipate. While you may not use it as often as eBay, it's amazing what you may discover here with an occasional peruse.
