Basically l got massively overcharged for two tickets l just bought to a gig in November - the site was full of hurry, hurry, hurry flashing messages and ticking count down wotsits and made it look as if there were only a few left, then stuck a £22 service charge on each ticket at the checkout. I paid because DS loves this band and it's their last tour but when l had a look at another website afterwards they were about £70 cheaper for the same sort of seats ( without all the add-ons and mysterious service charges) 
AIBU to ask if there's anything l can do or is it just hard luck and be more careful next time ... l can't resell the tickets unless l do it via the site l bought them from and they take a cut and keep the serice fees so that won't help me much - l'm just so pissed off l let them panic me into paying loads extra!
