Excellent advice. Vendors can be under a lot of stress especaily big name and busy vendors Like Frank Matthews. Manners and politness cost nothing and they will appreciate this. Plus the tons of messages busy vendors get everyday must be hard. Rememebr most vendors will just be as dissapointed as you if a package doesnt arrive. As for selective scamming i suppose it does go on sometimes but there is no point as more happy customers means repeat business. I believe when you are busy as Frank there will be the odd mishap, it is bound to happen.
