Linens n' Things again has sets of 2 Riedel "O" Wine Tumblers marked down to $19.99 from $24.99. Plus, new 20% off one item coupon code 173513239356 (expires 3/31) cuts that price to $15.99, matching the best I've seen for most sizes. Several sizes, from cabernet / merlot to reisling / sauvignon blanc, are available. Consider free in-store pickup as shipping is $6.99 and using in-store pickup allows you to place several orders, re-using the 20% off one item code.
