And so it begins. Recently, we at Foodista blogged about how Extreme Couponing is ruining things for the rest of us, and here is a great example. 
Publix is implementing a change to their coupon policy. 
Spokesman Dwaine Stevens would only say that the intent is to provide a consistent policy, but consumer bloggers have speculated that the policy is in response to extreme couponing tactics such as "stacking" coupons — using more than one per item.

Although not unreasonable, the change to Publix's policy shows that stores are starting to close up the loopholes that are being exploited by some coupon users.
