Yup sounds about right, you only have to search on UK popular forums like Muscletalk and UGM to find out how badly they are rated.
There are some highly recommended retailers but they are small fry usually SME#s in between 3-10 guys running the show.
Not sure what your business model is and what your margins are but im assuming this wouldnt be an avenue of choice for GD.
Think it would be a big hit in the UK though, especially given the amount of people seemingly throwing money at an inferior product (imo) that is NO explode.
