I have also had no problems with vet uk. I received an e-mail from them today aying they had moved premises.
Here it is:............................................................................
Vet UK would like to let all our newsletter subscribers know that we have moved to much larger premises.
Our new address is
Unit 11 Keld Close, Barker Business Park, Melmerby, Ripon HG4 5NB
This address is effective from today for the posting of original prescritpions to our prescription medicine department.
A huge bonus of our new location, being only 5 minutes from the A1 / A61 junc tion, is that you can now collect your food and save the courier fee.
A couple of rules though: you MUST always buy from the site first and then wait for us to confirm we have it in stock for you to collect BEFORE visiting us to collect your food order. This confirmation email is in addition to the order confirmation email you will receive after ordering. i.e. place your order as you normally do but select the free / collection from Vet UK option during checkout. The email sent to you will confirm your items are in stock and how to find us.
Again please do not turn up without having first had your order confirmed to be in stock and ready for collection.
Maybe this is for collection only?
