BevMo nickel wine sale is on!
To check prices, either bring in flyers from other stores (kind of tacky) or use the Drync Wine App on your iPhone or iPod Touch. There is a free version or you can upgrade for $5. I checked the prices of three wines I know the prices of and two times the app was spot on. The price for the third bottle was a bit high, but I'm used to buying it at Costco.
On a related note, if you live near a Trader Joe's check out the La Granja 360 tempranillo from Spain. The bottle has a picture of a pig with a string tied to each hoof. LaGranja is a nice light wine, kind of like a bordeaux, for just $4.
Caveats: gotta join the BevMo free loyalty club to get the discount. Unclear when the sale ends.
