Oooh, i have just started using Asda as sainsburies kept replacing my orders with expensive items adding sometimes as much as £30 onto our bill.
The first shop, we got 4 bags of cat litter instead of two, and last week we got two 24packs of Pepsi max instead of one!
I find sainsburys do that too. I suspect they do it deliberately espec. with special offers, e.g ordered 84 dishwasher tabs which were half price so £9, they subsituted them for Fairy ones that were £14.
Aren't they awful!! I swear Sainsburies did it every week except the first order. I'd had enough after i ordered bumper packs of Huggies super dry at buy one get one free. Instead i got one pack of the superdry and one of pampers, so i ended up paying £22 instead of £9.99. At the same tme i ordered a mega bottle of Persil on offer for £6 instead of £14 and i got the small one which cost £6. EVERY WEEK!!!!
