I approve Figrat, of your back passage, I grew up with an 'entry', door both ends. Also impressed by 'bloke', any chance send him over this way?? As for the raised bed find, you lucky s*d! 
Jean on-line grocery shopping is good. I've used Tesco monthly since Jan 08 when not allowed to drive. In all that time only had 1 bad experience- glass bottle of oil broken over all my & others shopping. Customer service brill on that occasion & also the time had duff (very offhand, rude) delivery driver!
Seriously I do a monthly 'stock shop'. All the heavy items- tins, bulk buys etc & sometimes fresh veggies, but take care you dont get just 1 carrot instead of 1 pack!
No petrol cost, wonky trolley, bad back from loading/unloading trolley/car etc or hassle over parking spaces. Today he bought the crates into my kitchen when I explained that my back was playing up again. (memo to self -dont try to lift large pot of Choc cosmos without bending ze knees!)
You're less inclined to 'impulse buy', still get good deals. Your favorites are stored & you can even do a list for future orders if you want. You choose a 1hr slot, some pretty cheap, to suit you. Wouldnt use it for every shop, but a lot less hassle for the 'big' ones. Just takes a little forethought, a decent running list of 'stock' items & a well-trained family (Ha) who leave empty packets or note when last of the item been/being used!
I've even been in the greenhouse, left a note stuck to front door & they come to call you if not heard the van pull up. 
Right, rest of spiders await, just had an apple break. J.
