they really dont know if theyre fake or not, the only purpose of selling those cards is to maybe get medicine, or just have food and clothes on the table really. (no hate)
I got one friend he buy pokemon card from mama shop for a few years and 1 pack cost 5 DOLLAR and be buys 2 everyday. So I went with him to buy cuz very cheap 5 dollar 1 real pack but then when I saw I told him it was fake and he dint know it was fake. Rip his money
Rip his money indeed. Some of these are easy to spot. I mean i buy fakes when i was a poor kid. Never saw real cards until i staryed working. But i still know is fake.
Same is the situation in india i have so many memories with fake cards from such shops and thats what eventually got me into real cards and even today when i come across such shops i endup buying 2-3 packs
