These days I find PAH is only worth shopping from if the things I want are on offer. Their standard prices are high. Even things like JWB are only as good as online prices when they are 30% off.
Since our local sorting office closed, followed by our local PO, I only really order from Zooplus and Viovet as they both offer the option of delivery by DPD. I love that you get an email the day before delivery - even on the day, you get another email giving you a one-hour time slot - you can change the day or delivery address if need be. I'm quite lucky as if t turns out on the day that I am going to be out, the girls in the vets next door let me have stuff delivered there.
I keep meaning to try Zoofast - the food prices are very good, although litter is expensive. They are based in Poland. A few people on the 'Cheap Cat Food Deals' Facebook group have used them, so they are genuine - they are based in Poland. They are the only company I know of where you can order 400g bags of Fibre Response.
Which reminds me - Don't forget that the Morrison's 2 boxes for £5 deal on AGAIl/Doubly Delicious ends in a few days. Well worth a stock up.
PS Val - Have you tried Sanicat professional clumping gold from Zooplus? - I have been using it for the last couple of years and it is the best clumping litter I have tried by far. They do a pack of 3 x 6kg for £12.99 - not sure how that compares with PAH. If you want to trial it, larger Tesco stores sell it in a smaller 5kg box for £5.49.
http://www.zoofast.co.uk/royalcaninfibr ... 16815.html I think it is normally around £18 elsewhere. They also so a 400g bag for £3.84, which is handy if you just like adding a few kibbles a day to regular food, which is often enough.
