HEB has all prices listed on site
I didn't see this posted so I thought I should post it for those who stumble upon this part of the forum and didn't know. HEB lists all their prices for their stores online on their website. It's extremely helpful when you want to price match that item with a coupon against the cheaper off-brand item or to see if the combo loco really is all that loco(Hint: they often over price the meat in the combo locos and you usually can get the same meat that's reduced price and avoid getting the fluff items you probably weren't going to buy in the first place.)
There is also a sale section online for items that prices have been reduced. Again use with caution a lot of times there is another brand for cheaper but the sale section is great for produce. I have often found some organic produce listed there that was cheaper than regular produce.
