Promotional codes for the auction site eBay.com allow shoppers to take advantage of discounts or special offers such as free shipping when buying certain items. However, these promotional codes usually only apply to certain products sold for a fixed price rather than items up for auction.
In addition to its auctions, eBay also allows retailers to sell products through its storefront for fixed prices in a manner similar to other online retailers. These products are typically eligible for the special offers or discounts offered through promotional codes available at sites such as Groupon at the seller's discretion. Savings from promotional codes can be substantial, with some items marked off 90 percent or more from their usual Buy It Now prices.
