Well, I’ve been at it for a couple months, expanding my followings and keeping an eye on feeds. I’ve bought two books that were reasonably good deals, but nothing to write home about. I’m finding myself looking at it less and less, and frankly slowly losing interest.
If you want to pursue a deal via Instagram the best course is to branch out your network to less mainstream folks (non-dealers/collectors that infrequently sell). More obscure the better... Otherwise expect GPA, which is understandable from a seller’s POV, but personally I might as well buy on eBay if I’m paying full market value (buyers protection, ebucks, coupons, etc..). I’m actually finding myself wanting to unfollow some of the bigger dealers because they consume my feed...
In short, you aren’t missing much...and there’s “no place like home”...aka the CGC forums. Besides the transaction side of things, the sense of community and legitimate content of thoughts/experience exchanged is unparalleled.
