e-transaction - Buying and selling stuff online like it’s a game and you’re

Buying and selling stuff online like it’s a game and you’re trying to beat your friend.

I bought a video game for $60 and my friend bought it for $10. I was jealous.

I sold my old phone for $1 and my friend sold his for $100. I was embarrassed.

I bought a shirt online and my friend bought the same shirt and it was cheaper. I was mad.
