I hate shopping that much that I tend to go in for about 10 things, get 'em, and get out. If I need another 10 things, it'll be in a few days time. :lol:
And just to note, I have the app as I thought it'd speed things up, but never used it after it took me longer to type in the shopping list than it did to buy the damn things inc traveling to and from the shops.
My mate apparently has his account stored on there and it suggests his shopping list based on his last shops, and he just removes stuff he doesn't need that week, and he gets it delivered every other week. So he doesn't do a physical shop at all and replaces his stuff he's got in on-going. I'd guess that's exactly what Tesco and the likes want you to do, and it's a wise move IMO. But I've never done the delivery thing. As much as I browse online, and even make online stores etc, I just can't quite bring myself to search for the common things I buy, such as shopping, music, video games, clothes, whatever. Over the years I've learnt to go and feel/see 'em and see what the score is, then buy 'em.
