Need to work out if I give them the benefit of the doubt and it was an innocent mistake, or whether they're trying to extract 3/4 tubs of adhesive off me @ £20 a go
Or if you do let it slide, just see how much they bring in and use and at the end of the job question it. I usually wouldnt give a price for a job with an itemised bill personally as you can then run into this problem.
Thanks, that's really helpful.
