OP: perhaps your mistake is acquiring needed items from a strangers forum post?
[INGO is a nice forum but it's still the internet.]
Buying something you need is typically reserved for retailers who provide customer service and support.
I'm only here to buy things I don't need from people who also don't need said item.
Be courteous.
Start a conversation.
It's a value proposition so if the answer is "No thanks"
(Or in your case No reply)
Oh well, they get to keep the stuff they want to get rid of and you get to keep shopping for stuff you don't need. Win-Win
I've had the pleasure of doing business with alot of cool people on INGO.
I've scored a lot of neat stuff in the process.
Yeah I'll drive across the state on my day off to drag home somethingfun.
(Hello, I'm here, and I have a problem. )
But I don't think I've ever had the slightest care or lost any sleep over a forum purchase.
My suggestion, have fun.
