BTW i bought two cheap fake miners yesterday while drunk, then had a strong and logically motivated remorse and this morning i claimed mastercard asking for chargeback because of "mistakenly hitting the buy button" (it is in the list of allowed motivations for asking a chargeback)
lol
imo - you have to do some DD... a lot of the "too good to be true" sellers have pictures watermarked from other people's stores... compare the "store number" on the pics to the actual store number of the user..
Some will even post fake pictures of feedback... if someone has zero feedback, that is a red flag.. esp if the price is super low.
I've also noticed sellers will also bump up the "weight" on a product to collect even more for "shipping and handling"...
