If nothing else... eBay Inc. (NASDAQ: EBAY) users are a feisty bunch. After just coming off a multi-week sellers strike, they are already planning their next revolt, tentatively set to launch May 1.

The most recent strike was orchestrated in reaction to recent changes made on the site and lasted from the week of Feb. 18 through last night. While eBay is steadfast that the recent site boycott had no effect on its business, not everyone is buying that, and are anticipating hitting the site again come May.

Some statistics have shown that eBay witnessed a 13% drop in its online listings, but eBay denies any impact. The site claims that the statistics out there are not taking into account a 20-cent listings promotion that it had launched just prior to the boycott that temporarily inflated its auction listings.

For the past several years, eBay (NASDAQ: EBAY) has pretty much cornered the market for online auctions. It has created such large barriers of entry, that smaller sites have difficulty breaking into the market. But this week's seller boycott on eBay has opened the door for some smaller companies.

We took a look earlier this week at the reasons behind the current eBay strike. We made note at that time, that some of your bigger name competitors, such as Overstock.com (NASDAQ: OSTK) were going to be capitalizing on the sellers' strike, but now we are also starting to hear about gains made in some smaller companies that you may have never heard of before.

In a recent article from Seattle Post-Intelligencer, two Washington-based companies said they have been loving all the negative attention that eBay has been receiving as of late.

If you are one of the upset eBay (NASDAQ: EBAY) sellers who has decided to boycott the popular e-commerce site this week, don't think that you have to lose a whole week's worth of business. eBay's competitor Overstock.com (NASDAQ: OSTK) is looking to reel in your business.

In case you missed it, eBay has definitely been ruffling the feathers of its users with the company's newly announced rate changes, and its sellers have decided to join forces and boycott the site all this week. Well, one site's misfortune could be another site's gain, as Overstock.com is trying to lure in disgruntled eBay users by offering them up to 50% off initial listing fees all this week.

While Overstock is officially claiming that the promotion falling during the eBay strike was just a coincidence, you really have to wonder how much truth there is in that. With eBay users showing their disgust over the new fee schedule this wekk, it seems like perfect timing for competitor Overstock.com to jump in and offer such a hefty discount. You can find more of the promotional offer details as laid out on the overstock website.
