Not currently on any bike shop mailing lists, but having bought a few work shirts from both TM Lewin and CT Shirts, they seem to almost communicate, every time you get an email from one, 5 mins later their competitor emails.. Sometimes more than one a day (it seems anyway.. i haven’t actually checked)
The most annoying however must be sites that email you if you add anything into a shopping basket. I may do some late night phone browsing and add a few things into a basket to check and maybe buy another time.. *ping* email – “you’re forgotten something.. checkout now…” F&£*$ off!
