Has anyone used this service? There are rumors that Walmart will be phasing out price-match and/or BOGO price-match (in Florida) in favor of Savings Catcher. I don't shop at Walmart (at least not for pricematch...way to frustrating!), but I'm wondering if Savings Catcher is a good alternative? If I don't have to deal with belligerent Walmart staff, I might actually divert some of my business there...especially since we have it on good authority that Publix is changing its coupon policy.
