I got accounts with all main merchants and play them off against each other on prices through their reps regularly, but prefer to give as much as possible to home grown local merchants that often beat the national mobs prices even against the bigger buying power they have ! But bulk buying of beads, scrim, dpc, DPM, wall starters, fixings and some other stuff is far cheaper from up north with wack, r&j or UK hardware which I play them off against each other too !
Wickes is ok for bags of cement evenings and on Sundays but Thier all in is yellow crap !
B&q are a joke but handy for one things.
Travis are shyte !
Jewsons are the Harrods of merchants expensive but available cheaper elsewhere.
IMO !
