Hadn't come across these guys before, but they had the best price I could find for a pond filter / pump, and they had good reviews on Google Shopper, so I thought I'd give them a try.
I was pleasantly surprised...
I was not too impressed with the attempts to automatically add a "voluntary" carbon offset fee, or a surcharge for using PayPal, but once I'd cancelled out of the transaction to fix those issues and completed the order, the notifications and tracking were beyond compare.
The item arrived very quickly and well packaged. Excellent job!
