I managed to get a click and collect slot with Tesco last night when I logged in at 12.30am. I waited in a queue to access the site for a short while then snagged the last available slot for three weeks away. I think they allocate one day at a time three weeks ahead - three weeks is the spread of dates available.
I will still have to go out shopping at least once before then but can then use the order to stock up on items that I've used waiting. You can only order 80 items and there are restrictions on the number of certain products you can buy.
Interestingly, I had added some items to the shopping basket earlier in the day and by the time I went through to finalise the order last night, twelve items were unavailable. But the system was able to offer some swaps to other things, many of which were acceptable. I will now have to check my delivery at the latest time I can before it is picked so that I can amend it for any more unavailable items.
I'm also keeping a note of additional items that I might run out of in the next three weeks, such as toilet rolls, butter and eggs, I have plenty for now but might need more by the end of the month.
For me, this delivery will mean that I can get the heavy items which I struggle to carry from local shops due to mobility problems - I have done online bulk shops every few months for years. So I am not jumping onto the bandwagon nor stockpiling! Mind you, I'll have to work out how I can carry all the bags from my car into my house - I'm thinking of emptying them into my shopping trolley while sat in my car!
