You know how when you do your grocery shopping online and Tesco dont have the tinned tomatoes you want instead they send you a box of dishwasher tablets and say " we thought you might like this as an alternative"?
Well I just bought a rope sheep halter on eBay and when the order was confirmed they suggested some things to "compliment" my purchase.
Those things were a large stable block and a log splitter to go on a tractor!
