Upcoming sale on Coke 2 liters at CVS! Stock up price!

CVS is going to have Coke 2 liters on sale July 3-9 for $0.69 EACH (limit 5). My recommendation would be to take this ad to Walmart and price match because you won't be limited on your number. If this is something you really would like to stock up on, I'd also check on coupons since you have time to get them. I'd recommend eBay. The only coupons I'm really seeing on there are "Buy 3, Get 1 Free" which would make each 2 liter $0.54 after taxes. Be careful though that you aren't ruining your savings by overpaying for the coupons!
