Pricing reference for your supplier's

I am curious, because of potential geographically differences (especially for b&m stores) where do you normally buy coins and what pricing reference does your supplier normally use: greysheet, CPG, pcgs, ngc, red book, blue book, completed sales on auction sites like eBay/great collections,………
Also, some of my lcs say that greysheet is the retail price. 🤔
I will go first. I normally buy from a few lcs and I pay greysheet or less.

I buy online (no LCS here), either dealer sites or ebay etc.. I have no idea what price guides are used. I do research if the price looks hinky.... Cheers, RickO
Combination: LCS - generally greysheet or below depending on the coin. Auctions - again depends on the coin and how badly I want it but a combination of completed sales, Heritage ( I check greysheet on Heritage) & EBay, PCGS, Numismedia.
The way the market has been I don't think you can use just one source
I use pricing reference apps off my phone. In addition I look at population data.
