"enabling a filter for meat shows recommended items from other categories above the meat products"
"clicking on page 2 of results resets all filters"
"searching for item X returns a list of results that does not contain it, but navigation shows it clearly exists"
etc.
How can it be so bad??
My favorite is when you add a filter when you're on page 2 and now you're on page 2 of the filtered results.
Want me to on board? Probably 70 percent of every grocery trip is the same essentials, so just let me scan my recipes and offer the opportunity to quick select from that list of items next time.
If you want to feel real pain, try using the grocery apps or similar on slow cell signal; it's death. No! I do NOT need a 12 MB image of the bottle of milk I buy each week, I just want to see if it's back in stock!
I'm presently grocery-shopping in another tab, and I am continually amazed at what a terrible UX I put up with. Compare any grocery website to McMaster-Carr and it's not even 10x, it's like 100x worse. But I give them my business because the competition is actually even worse.
