You betcha I do, as OFTEN as possible !!
I've come across some of the best shops EVER on our travels ... sometimes I just spend a little, sometimes more - but it's just neat to see the different shops and all their "personalities". I used to travel for business and visit shops whenever I could squeeze one in ...
DH knows it's a must for me, like his visits to the local tackle shop or fishing spots - I check those out with him (I like to fish too) ... and we've often gotten the BEST tips for local food & sightseeing from our little stops along the way :)
