Chedraoui vs Soriana

Hello
Quite similar offer, prices will differ specifically on certain items, for example Greec yogourt is a lot cheaper at Chedraui. Chedraui also had 25% discounts on wine and liquors 2-3 days before Soriana did.
We get most if not all of fruits and vegetables and fish around the market so I can't really comment on this.
They are next to each other, I'd suggest you visit them both one day with your own grocery list and favorites for you to be able to compare.
The best thing I've noted it that Soriana has been adding cashiers since Chedraui opened. Last year they only had 2-3 opened to push customers to use selfcashier. But it's not easy when you've got a full cart with 40-50 items.
