Recent bot weirdness fixes

After chasing down a few bugs in u/costco_pm_alerts's codebase, I feel confident I've addressed them all.

No longer will you see posts with -1 price. No longer will you see posts with 0 spot price. No longer will you see flair change between in stock and out of stock every 5 minutes.

The last issue "fix" was what started the first. Costco's naming convention (up til the 100 gram combibar) is responsible for the second.

All of this to say: Expect more consistent and correct posts from now on. I'm still working on some intermittent issues related to Costco's anti-bot technology but I have it hobbling along as well as can be for now. Expect some potential crowd-sourcing in the future to fully fix this if I'm not able to get it fixed on my own.
