You're supposed to Say"I'll take it" please send Paypal info"
Usually around here it's the first, "Ill take it" wins.Some sales are very close in the times that were posted,so time stamps are important.
The seller isn't always 100% fair either.Sometimes the seller will "blow off" an earlier."I'll take it" 'cause he (the seller) got a better offer at around the same time. I hope this helps you.Welcome to the forum and good luck.
Best,Marc
