Solidity of Rainbows messaged me about it. Fortunately, there's still enough time to buy it!
Today's Groupon in Lincoln (but can be used anywhere since it's for web purchases) is for $40 worth of shoes and apparel from ShoeBuy.com for only $20. I've never been to the Shoe Buy site before today, but I was really impressed by their selection. I found plenty of cute shoes to enjoy during my window shopping. They also offer free shipping, free return shipping (if they don't fit), no sales tax and a 100% best price guarantee.
If you haven't signed up for Groupon yet, please consider doing so with my referral link. It's free to join, and you'll receive an e-mail each day with a special offer for your city. As of right now, this deal is available for three more hours. Check it out, and happy shopping!
