I do not get along with them very well....
A while back I bought a lens from them which was not focussing properly. Even with -20 on MFA it wouldn't focus accurately so it was rather misaligned. I returned it and they only refunded the cost of the lens. Forget refunding my return postage, they didn't even refund the initial sending postage costs which they should have as per the law.
So I refuse to buy from them unless they offer free delivery which sometimes they do if you ask nicely and sometimes they won't. There is an item on their website that has not sold for two months and I'd buy it if they offered free delivery. Given the price of the item most shops would in fact offer free delivery yet they choose to rather not sell it than offer me free delivery.
I do not think they have good business sense though they seem to have been in business forever. So may be its just one of those places I do not get along with (there aren't many, I even get along with
MPB!!) but everyone else seems fine with them.
