Common Courtesy

I have had a couple wanting big ticket items from me. They want my pay pal addy to pay me. Then the payment never comes and I don’t hear from them again. It kinda irks me for being led on for a month or more with them whining for a better deal. 1 guy I have bent over backwards and came down to his price. Now nothing. It’s ok as I can use the stuff in the spring. Kim
