Pay now, start profiting tomorrow. FF is safer than GS. Only Venmo/Cashapp.
I more or less buy regularly from:
ebay (I´d say this is like 2/3 of my entire tcg purchases)
cardmarket (for cheap singles that are not worth that much)
troll&toad (^)
gradedpower
dave&adams
cardkingdom
yahoo jp
heritage

I have used TCGPlayer and it is great, but since I’m not in the US, I must use a re-shipper. This means that sending multiple packages is annoying. Additionally, they must all have tracking or the company won’t accept the package.
I recently ordered $50 of cards and because there was no tracking I just had to accept them as lost.
Singles: Ebay (Primary) LGS, Local Trade (Preferred)
Sealed Product: Modern (I pre-order a case to open from normally my LGS sometimes online as my LGS is an hour away) Vintage: I would of said ebay, now good luck?
Sleeves etc.: ebay bulk 1000+
