For most of my bulk buying like sinkers and swivels, I try and use Cabela's, but some things they just dont carry in the larger bulk packaging.
GI Joes is close and convenient but the one on South Hill has been really inconsistent on their ordering as of late. Im usually in there a few times a month so I know whats on the shelves. Many times I have seen items go on sale that are not even on the shelf.
"Work,Sports & Outdoors" in Orting is where I have been trying to go lately when I can get down there. They might not have the huge volume of inventory like the larger stores, but their prices are very competitive and the owner is a super nice guy.
