Good service and prices.Some products give customer reviews, with no holds barred.If you go on their mailing list, even more special weekly/weekend offers available. Go for it, and perhaps you may save that extra pound or two.
Some people have problems,especially with returns. But when you have thousands of customers,and deal in large quantity daily deliveries, there is always the possibility of a weak link, in the system. Personally I have never found this 'yet'.
