Popped into Poundland yesterday, can sometimes find a bargain.
Epoxy glue, £1 instead of the usual £5-£6 for branded stuff. A bit awkward to get into – you have to snap out a little tab between the plungers and cut the cap off the applicator end with side-cutters or similar. It's not fast curing, takes a few hours but sometimes that can be an advantage. Doesn't say on the pack how much is in it but size is similar to other syringe type epoxy.
Also got some little clamps (4 for £1) good for up to about 3/4 inch, any thicker and they tend to slip off. A steel 24" rule, quite thin but a straight cutting edge for longish parts (you've guessed it, £1).
Bargain!
