I've been passively aware of it, but don't really care - most items are not really egregious. Because Safeway's prices are so volatile with sales and Instacart doesn't seem to really reflect that, it ends up balancing out pretty well (plus, of course, the huge convenience factor)
EDIT: Eridius is correct below. Instacart is just mislabeling their product pricing. The 3 lbs. ribeye shows up as $30 per lb., but is actually $30. I'll bet they are doing the opposite as well (buying 0.5 lbs. of anything will look like an insane deal).
ORIGINAL POST:
I'm looking at some $30/lb ribeye steak right now. The same "extra value" package at Safeway was $10/lb.
Are you sure you're looking at the same thing? I just compared some ribeye "extreme value" steak on Instacart vs Safeway's website. Instacart has the 1.50LB package at $15.74/lb. Safeway has it at $9.99/lb as the Safeway Club price (for some reason it won't show me the non-club price). That's a 50% increase, against Safeway's discounted price.
Except oops, no it's not. Instacart does say "per lb", but if I add it to my cart, the final price is actually $15.74, not the expected $23.61. Which compares to Safeway's club price of $14.99. That's a 5% increase, which seems quite reasonable.
