WTB/WTTF Sig Xmacro 17 or 21 round mags

Looking for a couple 17 or 21 round mags for the six xmacro comp. I’d like to be around the $30 per mag mark. Hoping I can find someone in the forum before Black Friday deals hit. Let me know what ya got! Located in Oregon (not a ban state yet). I have Venmo and Apple Pay.
