Where can you buy you girls mermaid tail for a low price?
eBay,criag list, bing , goodwill or outlet
Sorry to say you cannot. Mermaid tails can be made for about 70 dollars for the fabric and the monofin of your choice. Prices range when MAKING one. I suggest that, because the easiest buy I've seen was mermaid tail on Ebay. They have large selection colors, but the price is about 110 dollars. Look up "How to make a mermaid tail" on youtube.
