Indeed, I've probably purchased stuff for a few hundred 's at process-supplies until now and they are both quick and professional to deal with.
The only "oops", is that if you live outside the uk and order liquid chemicals, you may need to call them to arrange shipment costs. I did that once (I didn't know better) and the shipment became more expensive and slower that way because of the security issues related to that, but I received the goods just fine and they were packed securely.
