Made it home with a new transmission jack and creeper
Since it's Harbor Freight, I couldn't walk out of there without some cheapo items. So I picked up two 4" paint brushes for $1, too
Also, they honored my 20% off coupon on the sale price. The coupon says it's not valid for floor jacks, but I noticed online they have floor jacks and transmission jacks in separate categories. They confirmed this for me when I called ahead
