There's a select chained shops here selling these empty cans for $5 each. Labeled as "Vintage Tin Can". I wonder what's the meaning of "vintage" here? And how/why someone can do business like that thinking that your customers are blind? Or just whatever possible way to cheat your customers? Just to share some information, this tomato paste is still selling outside for less than $2 a can, and you can get it with nice whole tomato paste inside too!

Also, they took some cups/trays from Daiso (for your information again, Daiso sells everything at $2) and selling for $15. 

Holy crap!
