Buy me a bulb!

Hi! Every year for the last 5 years of running my free SAL I am repeatedly asked if I have a 'buy me a coffee' type thing available, so this year I'm adding this here. Please remember there is no obligation to do this at all, it is just for those who ask and would like to! I've set it to a £1, but you can adjust the quantity if you wish! Thank you in advance!
