......According to the way The Exchange has operated since I've been here is once you say "I'll take it" you have bought the item. If you do not have the funds at the ready, don't commit. Granted the deal is not completed until the buyer is satisfied, but committing to a purchase and being able to complete the purchase in a timely manner is the buyer's responsibility, not the sellers.....
I understand where you are coming from, but I would like to make two points.
1. Lets say your method was applied here. At the end of the day the seller would have still lost a sale and the only change would be negative feedback for the assumed buyer. So, the seller has NO benefit.
2. For the most part, sharp and pointies are a hobby, a recreation. Life has a funny way of creeping up on you at the most inopportune times. There are a number of ways that a person could honestly get hung up when trying to secure funds for a purchase. So, I believe it would be unfair to punish someone who may have legitimately had good intentions. With that said, I believe you are right when you say a commitment is a commitment, but, a seller has to prioritize his sale. Either be more interested in the concept of a sale, OR, be more interested in the sale itself.
Back to this particular situation. Buyer 1 says he needs time to load funds...thats all good, give him till the end of the day...hours, not a day or two. Buyer 2 shows interest, perfect, a back up. Inform buyer 2 of the SHORT timeframe and that you will be in touch. If Buyer 1 comes through with money, great....send message to buyer 2 stating the item is sold. On the other hand, if buyer one DOESN'T come through with the funds by the end of the day, send buyer 2 a message that item is available for purchase.
Efficiency is the name of the game. Again, I totally agree with you in that I believe a persons word is important, but, im not going to hold up my sale for an extended period of time based on someones word.
Thats just me though.
