Here's a perfect example.
I listed my 2016 Topps Update Series Baseball ASTIT-RC Robinson Cano trading card for only $2.99, which is approximately 71 percent cheaper than my competition.
A stingy buyer offered to purchase that card for $2.70. I was going to accept their offer -- but someone made an instant purchase before I made the acceptance! That's about as ironic as it gets!
The hobby is plagued with stingy buyers who tries to abuse the deeper discount option. I personally only use that option if I'm offering to purchase multiple items...
