Why are Texas flags less expensive...

[wild-bill]

...than most other state flags? Is it a quantity thing-because more of them are sold than other state flags?

Bingo, I think you have it. Or it could be all the flags they sell to Texas Roadhouse.

From what I gather, Texas are very proud to display their state flag, and with anything the more they make, the less expensive it becomes.
