Shopping List-Need Help with PCs

So I have a short list of things here that I plan on buying sometime in the near future and I need some help with prices. If you know any of the prices for the following items, please comment. Your help is greatly appreciated!
Plain-colored Yuni Potion
Halloween Costume
Plain-colored Rusty Potion
Cheapest Chibs Potion
Calico Costume*
Fire Costume*
Angel Costume*

*Mostly curious so I may compare these prices to possible temple costs, so if you happen to be selling these items, please don???t get your hopes up.

I???m also curious as to the approximate value of a complete set of instructions for the Enchanted Plushie Machine, and some opinions on how soon/well you???ve made your money back.

Thank you for your time and help, and, if you happen to be selling any of these items, I hope to be your customer sometime soon! ^.^
