i use tescos all the time i have recently started doing my shopping list as i need things or run out of the regular items, i then book my slot after making sure i add the right amounts for offers,(never assume that bogofs are automatic if you dont add 2 youwont get the free one and so on) i mostly click no substitutes, i recently ordered some fresh meats and stuff and on the notes put on i didnt want short dated products and was very suprised that my picker did find me good dates lol once i have my approx total i then ring my bank and ask them to transfer the money over from my account to my internet use account,
tried asda and they let me down three times so wont use them at all, tried sainsburies once but found them dearer than tescoes
