I bought a pack of 10 off 2.4m plasterboard edging strips for a small job I had from Screwfix for £22.99 last week.  Their product code is 55587.  I've only used 2 1/2 of them so there is 7.5 off left (3/4 of a pack).  They're yours for £5.

Collection only from DE65 5AS, Ch8urch Broughton, just off the A50 between Derby and Uttoxeter.
