This deal has ended.
Amazon has dropped their price and now has sets of 2 of Riedel Wine Tumblers (stemless, as pictured) starting at $15.92 for chardonnay glasses and $19.92 for cabernet. Riedel is premium glassware and wine tumblers are quickly edging out stemware. Shipping is free if you spend $25. Also, think about creating a full set by spending $125 because then you can use their $25 off coupon, which is an extra 20% off, effectively.
