Vapefly RDTA Galxies

I would like to acquire two Bottom Feed capable Vapefly Galaxies. They come with interchangeable center pins, one for use as a Tank, one for Bottom Feed Mods.
Looking for one Black and one Blue.
Will pay reasonable price, or possibly trade for homemade Naturally Extracted Tobacco flavors (extracts only, you would have to mix into E-liquids yourself)
