are to be avoided. Only two items in a three item order arrived, no paperwork in the package. Two emails and two weeks later, still no comms. A Paypal case got the owner's (Paul Bradbury) attention and his lame excuse was that their email wasn't working and they were out of stock (remember no paperwork). WTF?
To be fair, the price of the missing/out of stock item was refunded.
