So I found this thread not realising CEX would sell the straps. I want a Saddle Brown Classic Buckle but they didn't have any in stock so i settled for a Brown Modern Buckle.
It was grade A and only £45, not bad considering they're £209 retail. Anyway, I took the plunge as it said there were 9 in stock. It was shipped on Friday and turned up today. I'm amazed, the cardboard box was open and pretty banged up but the strap was in it's plastic hard case, still with all the wrapper on. Perfect condition.
Really happy with that but after seeing a lot of other posters on here, I'm concerned that I wouldn't have the same luck again!
