How are the prices on our featured eBay stores so low?
All of the eBay listings featured on this page are Brand New items in their original packaging, unless the listing page explicitly states otherwise.
  • Many listings contain photos of the actual item that is being sold. To browse through these photos, simply click on the relevant "View Deal" button.
  • Every item sold on eBay is covered by the eBay Money Back Guarantee, which protects you in case you do not receive your item, or if the item and its condition are not as described in the listing. You can use the Money Back Guarantee up to 30 days after you received your item (or when you should have received it)
  • If you're paying with Paypal, you will also be covered by Paypal's Purchase Protection that is valid for a 180-day period after making your purchase.
We only feature listings from established U.S.-based eBay stores that earned positive reputation from their customers.
  • Our featured eBay sellers have worked hard to build their positive reputation, and will not risk undermining it with a negative feedback by attempting to sell anything different than what is described on the listing.
  • By clicking on the seller's name on the listing page, you can easily view their recent feedback history and read comments from previous customers.
The low prices you see for our featured eBay listings can be attributed to multiple reasons:
  • eBay is the world's largest online marketplace, where multiple sellers in every niche compete with each other daily, which often means engaging in price wars to win more customers.
  • Many eBay sellers purchase their products directly from the supplier at wholesale prices that are not available to the general public. However, contrary to major retail stores, these sellers have significantly lower operational costs, which allows them to sell the same products at much more competitive margins.
  • eBay's own operational costs are lower than other online competitors such as Amazon, since eBay does not have to maintain warehouse facilities, as eBay sellers handle the shipping process on their own. Therefore, eBay can afford to charge their sellers with smaller fees, which eventually benefits the end-costumers.
  • Most eBay sellers are not bound to MAP policy (Minimum Advertised Price) which manufacturers often require from high-profile retail stores in order to upkeep their brand image.
  • Sometimes eBay sellers offer brand new items that are an overstock liquidation from a company that just went out of business.
Remember, If for any reason you're hesitant about purchasing from a particular seller, you can always browse among the other sellers we feature and find the offer that suits you the best.
