Spice variety is definitely an issue and sometimes when something is available like Hungarian Paprika, a tiny bottle can cost as much as $3, and I mean tiny. The key is if you see a spice at the supermarket and it's at a reasonable price, get it because they run out. I passed up on that chance with McCormick cayenne pepper and now I can't find it anywhere.
I know it was mentioned before but getting supermarket membership cards are a must to save money. I think that's one of first things people should do after settling in their city. I got the supermaxi fairly quickly which is also good at Megamaxi but procrastinated with the Mi Comisariato card which was a mistake because the savings for some items are even bigger than the stated members price. But better late than never but had I not procrastinated I probably could have acquired enough points for imported knives they were giving away for points.
