I don't think grocery retailers "raise prices" across the board. I think the "charity bundling" concept is just for P.R. The company presents the big check at the end of the campaign, and the public then credits the company, even if the company itself contributed nothing beyond a little (deductible) personnel time. The Ronald McDonald House perfected that mechanism. Some retailers used to do the same with pooling customer MDA donations, then showing up to the telethon with a big check... with the company name on it.
