How to make use of spare research budget? I have a £1000 of funding that I can use for my research or teaching. I have bought a few books with it, but I have no other immediate necessity (conference trips etc). I do not like the budget to lapse (by the end of this July) and I am afraid I may have looked past some potential benefits I could have gained using the budget.

What are some possible ways for me to make use of this sum in this limited time?
Spend forward (into 2018-2019) with opportunities related to the research which originally got funded.

Why not top up with a last-minute research trip, or a write-up trip completed and paid for by the end of the grant period?
