ebay purchases

how do I get this to give something back to the t-bar, by buying off eBay? done it a few times before but I have forgotten how to do it, any help please, :broon:

The very top post in the Pitstop is Ebay Purchases - Site Upkeep.

The 1st entry on the first page is a video created by Leigh which explains it better than I ever could. It's simple and works.

How much income it generates, I have no idea but owt is better than nowt!

thank you, Bruce. I know where I went wrong now, I will use it when I buy my halo's for my front lights, PS the water alarm is still working ok and I have had no problems with it.
