Cost Plus World Market, one of our favorite places to go for good wines at great prices, has the 2008 Pacific Rim Sweet Riesling and the 2007 Pacific Rim Dry Riesling for $7.99 per bottle.
A rebate form attached to the bottle offers a $10 rebate when you buy two bottles, so if you fill it out properly you're only paying $2.99 plus tax for each.
Pay attention to the terms and dates of the rebate. For this particular offer, you'll need to fill out the rebate form, write the UPC numbers from the bottles on the original receipt, and include the receipt.
Pacific Rim is a winery owned by Randall Grahm. Randall's other winery is, of course, Bonny Doon.
Happy Savings!
