I've seen them a few times in the NE but not frequently. When I did I believe they were Herr's. I gotta tell you though, Lays ketchup chips suck. I've never been a huge Lays person in the first place but they're extremely skimpy with the seasoning on their chips.Ketchup chips!!!! We don't have them here in the states!! So delicious, I wonder why Lays only makes them in Canadia
If you're ever in Canada and want good ketchup chips, I can recommend two brands. The first will probably surprise you. Wal Mart's Great Value brand makes THE best ketchup (and all dressed) chips. They're also the cheapest you'll find anywhere. Second best (for over 2x the price) is Old Dutch, which is a Canadian chip brand.
