This is the latest freebie multimeter that I got for free. It might be the free one Denny referred to.
It comes with a battery. Put it in and test it before you leave the store.
I have to drive 20 miles each way to get to Harbor Freight. Many times they are of of stock on sale items (and free items). For that reason I usually buy on-line ($6.99 to ship any size order).
Sometimes they honor the free-item code when ordering on-line. Of course, if you get something DOA, you have to hassle with return/refund.
