About to move from TX from AL. Should I renew my permit in Alabama or get it done in Texas?

I ask because it's $20/year in Alabama and $40/year in Texas. My thought process is before I move I renew my AL license for 5 years and use that until it expires. I'm not seeing a down side. The address listed on my permit is at my sister's house where I currently live. She's continuing to live there for the foreseeable future via /r/CCW https://ift.tt/3mEeFlA
