Their offers are quite good, but I am going to stick with JWB - I can vouch for PAH's returns, they took back the bags I had bought in OCtober, and give me £12.99 back per bag, even though one was open and part used (I am sure I paid £13.99 - but as it was for two bags, and they refunded me for each bag, I wasn't goig to complain - I was also pleased at getting money in my hand to - even more so when I checked the receipt, they missed 3 things off it, and I am sure one of the things I bought had a higher shelf price) - my only problem about trying the other flavours there is that it is so far to go back and swap it, I only get that way once a month.
Mark, PAH do a light food - when Molly gets off my knee, I shall get the bag and check it. JWB also do a Senior/Light food, so you might not need to use Hills.
