Boyshort Swimsuit

Cute but inexpensive swimsuits?
I checked Target, Kohl’s, JC Penney and Walmart. So far, the cutest that I found is in Kohl’s($14.99/pc on sale) but the cheapest is in Walmart ($7/piece).
Is there any other shop that I should check??
What I want is a small sized halter neck and a boyshort style swimsuit.
Thank you!
Old Navy’s swim separates (mix and match) are currently $12.50 a piece but only until May 21st I believe. There are several different colors and styles.
You can find them in-store and online. This page has what you’re looking for (halter top and boyshort bottoms):
