Dill Fickle 2...Electric Booglaloo

This woman asks me about a sewing machine I had on Etsy. She says:

Hi! I'm interested in purchasing this machine, but was curious as to whether it had been in a smoking home or smelled of smoke. If you could let me know, I would greatly appreciate it. Otherwise, it looks beautiful. :)

I reply:

No smoking in this home and it's been in my possession for at least 15 years :)

She replies:

Okay. Also, I wanted to mention that my zip code would be -----. The shipping mentions that it's $37, but I know in the listing you said that it would be less for the East Coast. I'm definitely interested in purchasing.

I reply:

 If I ship via FedEx, the shipping cost would be $21.21. Via USPS, the cost is $32.00 to your zip code.

Just to let you know, FedEx cannot deliver to a Post Office box. All other addresses seem to be okay. Let me know which you prefer, and I can either edit the listing to show the shipping you choose or I can refund you the extra money after purchase.

She replies:

 If you could ship it FedEx, that would be great! I can purchase it now and have you refund me the extra. Whatever adjustments you need to make for packing, etc. are fine. Thanks so much!

She buys it, pays for it and then immediately cancels and says:

 I would like to cancel my order #---------, placed on Aug 7, 2014.

I apologize for the inconvenience and look forward to hearing back from you soon. After researching this machine further and taking a closer look at the machine that you have offered for sale, I have strong concerns with regard to the electrical cords and foot pedal. The foot pedal is completely different than I am seeing as would have been original to the machine. I'm very sorry that I didn't take a closer look at this sooner, and very sorry for any inconvenience this may have caused.

Thanks,

Oh no, no inconvenience. I only wasted my time looking the shipping up for your ass, and replying to you when I could have been doing something else that would have made me money rather than costing me another .20 fee to re-list what you "bought". The fucking cords on the damned thing are original. And anyway, if you're planning on using the machine and not just displaying it, then who cares what the fucking pedal and cord look like as long as they work? Fucking ridiculous.

Cancellations like this are my biggest beef with Etsy. They should offer a relisting fee refund for when you encounter a fickle buyer.
