Frosted Flakes...they're not grrrrrreat

I put some pony stuff for sale. Within minutes I get one "Claim". I open PMs and see that she and another person I have sold to in the past have both responded. Since ol' claimee was first, I give her dibs. BIG mistake. 

 She gives me info, I send the invoice. First, "Do you have anything else?" then "Can I get a picture of______?" and here I am almost a day later - unpaid. A little pissed. Yes. Another fuckin pony flake. Bitch, I was selling THOSE two things. If you want them...fucking PAY FOR THEM, then worry about what else Khajit has for wares. 

 Then I check my ebay. I have a pony on fixed price and see an offer. I check the offer expecting stupidity and I am never disappointed. A $55 offer for a pony I have listed at $100. What on God's green earth would make you think I will give it away for half price? No thank you.
