TradeUp.net caught my eye because of some cool loyalty programs, but there aren’t many reviews online. Anyone got experience, especially with TradeUp or something similar?
No, I've never heard of it.
But anyway, the way you mention the platform above sounds like someone trying to introduce it to everyone. I've seen several users do the same thing - it's worth calling it shilling?
I'm not sure what your real motive is, including the loyalty program you mentioned on the platform. Some people have been searching for the platform since you mentioned it in your post - is this part of a promotion or something else?
