oh the non discountable trick they did that to me for 3/4x15mm tap connectors over £5! I told them to stick it and went round to PTS and got everything cheaper.
I've used williams once good service and even with paying delivery for an early drop off they were cheaper. I'd love to use them for everything if they had one down here city plumbing are a rip off especially on the little things usually over double the price of elbows couplers etc. Next time I make an order I shall be adding a few bags of each to my list.
Ive finished with it now so I'll be taking it back for a credit!
