I've just been looking through the offer sent through by a product supplier.
Basically it's 10% off everything this weekend only.
Interesting I thought, I might just give that SPM a go on the back of it, BUT, I'd be better off waiting for a no offer week....why? Because you have to pay £10.50 postage on items below £75 and because the offer makes SPM £71.82 it would be cheaper to pay the full price and not pay postage
