Trader Joe's mini cooler bags sell out fast, just like its mini totes

Customers like Trader Joe's mini accessories so much that they are willing to pay hundreds of dollar for bags that retail for just a few bucks.

The grocery chain is now selling mini insulated tote bags in stores for $3.99 each after it quickly sold out of $2.99 mini canvas tote bags that proved so popular that they were selling on resale sites for up to 200 times their retail price.

The mini bags have become a mega trend, with the insulated versions listed for sale on resale sites like Ebay for up to $50 each. The bags come in two colors — "hot magenta" and "cool teal." Consumers are scouring resale sites just days after the bags were released and given that they are already sold out at some grocery stores, according to posts on social media.
