With the Target Web site down, eager Missoni for Target would-be shoppers have taken to Twitter to solve the Missoni mystery.

Target retail stores all over the country sold out of their inventory within hours or in some cases minutes of opening their doors to shoppers who had been waiting in line since the wee hours of the morning. Those who chose not to brave the crowds were out of luck: Target's Web site crashed Tuesday morning and has been up and down (mostly down) ever since.

While Target's inventory has been increasingly dwindling, eBay's has gone way up.

The blog Shefinds.com reported Tuesday at about 1 p.m. that there were 1,473 Missoni for Target pieces currently for sale on eBay -- pretty remarkable, considering none of the pieces have been available for more than a day.

When IBTimes checked it out half an hour later, there were 1,954 items.

By 2 p.m. Tuesday, there were 3,037 Missoni for Target items available on eBay, and at least two intrepid re-sellers had dared to tweet the sale of a hijacked item.

But they may not be successful. Angry Target customers are taking to Twitter to discourage people from buying Missoni for Target items on eBay.

@ChicDC202 tweeted: DO NOT BUY Missoni for Target on Ebay! These people are putting it on for over double what it retails for! NOT WORTH IT!

Indeed, the markups are significant.

The highest ticket items are the bikes, which are selling for as high as $1500. (An hour ago, IBTimes reported that there was one bike with a Buy it Now price of $2,500. Either the bike was sold, or the price was marked down.)

One Twitter user wrote that she witnessed women clearing entire rows of a Target retail store.

The eBay sellers may be left holding more than just the bag: Multiple Target retails stores have reported to their local media that they plan to restock, most within a couple of days -- but probably not today.
