Buyer warning

Documented buyer reports tie Alex Diaz to fraudulent activity: AI-enhanced listing photos that hide card damage, cards shipped in worse condition than advertised, refusal of refunds or returns, deleted listings, and blocking buyers who raise concerns.

Verdict

Alex Diaz built a following as Ballpark Alex while publicly advising the hobby on trust. Multiple buyer reports describe the opposite experience: listings that look perfect, cards that arrive damaged, and silence or blocks when problems are raised. We do not recommend buying from him.
