Well @ Costco for Southwest Airlines I never saw better than $429.99 for $500. They don’t currently have.
However, my sister just informed me that Sam’s Club has $399.99 for $500, limit 5.
And she said for those who use Instacart, $199.99 for $250.
Happy shopping. Ps that first link makes you show you’re not a robot b4 going southwest. Or just google southwest + Sam’s club.
Me - not a member - but I guess I will be soon!!
