Recommendation : Buyer communications requested within 24 hrs. of intent to purchase parts

Hello board members, I for one have been experiencing buyers for my parts that state "I will take it" and delay communications with me,
as other buyers sit behind them waiting. and waiting.... I am suggesting the board requires all members who want to purchase parts
contact the seller within 24 hrs. of the intent to buy, or the seller has the option of going to the next person inline without courtesy complaints posted against them.
I have been hug up for days on some transactions waiting on buyers to respond back to me, and one never contacted me on a substantial purchase.
That's my recommendation Thank you
