Shifters

So I ordered a set or SRAM Rival shifters from the cheapest place I could find (£20 cheaper than anywhere else I could find and a huge £140 cheaper than list price), what turned up were not SRAM Rival shifters though.   For some reason they had substituded SRAM Force levers at no extra charge.  Result.   This does rather force my hand to spend the extra fiver to get the matching force derailleur.
