This place has the strangest variety of all things man... You can find all kinds of tools (discount prices), supplies for almost every home/garden need, and knick knacks galore! (even bawdy humor gifts like whoopee cushions and fart machines). They are always running specials and sales that can be found in the center isles... This is always a fun store to go to when you need something (cheaper)... you never know what you'll find!
Some of the best buys I have found at Northern include garden hoses (great quality hoses at discounted prices), Wrench and ratchet sets, tool organizers, a motor for a wood splitter, wood splitters (for those of you that split your own wood the purchase is totally worth it), and grilling accessories.
