Evans Cycles - disappointing and frustrating online experience

At the end of May this year I decided I wanted a new short sleeve cycling top. Having bought quite a bit from Evans Cycles this summer (my new bike, lock, lights, cover, helmet, jacket, pump, water bottle and cage, gloves, ... and a few odds and ends) I decided to make my next purchase from them.
I scoured their online catalogue and finally settled on a nice looking top.

At the 'Select and Buy' stage it turned out that the size and style I wanted was out of stock. So I popped in my email address for an alert when it came back into stock.

Later the same evening I decided it would be easier to just pre-order the top and have it delivered for a store collection. How wrong I was...
