Late last year mskeggs shared on the forum [here] that somebody had forked a grocery price tracker and adapted it for Coles/Woolies. Personally I have found it extremely useful.
Unfortunately it hasn't worked for the past few weeks. The dev stated last night that it is due to Coles bot detection, and needs some help working it out.
Is there some Python devs here that could lend a hand?
Looks like it's already using Scrapling for Coles. Coles uses Incapsula and doing a quick googling there seems to be quite a few "tips" on how a scraper can beat it.
