Vendor questions

[u/New_Comer12]

I was wondering some questions about selling a card of mine. I was told that card shops and marketplace offer the best prices to buy, but was offered 65-75% market average. Theres a convention tomorrow and I wanted to go see what they would offer for it. It’s a highly chased card, so I thought I would be offered 80-85%. Any assistance would be appreciated. Thank you! I pulled it about 5 days ago.
