Too bad it isn't a Home Depot card. (Grin) You could have thrown another $100.00 down with it and got the a Rigid Oscillating Spindle / Belt sander. I am on my second one. I literally wore out my first one, I used it so much.
My advice, use that HF card for anything but a belt / spindle sander and wait til you have the money for a Rigid OSS. Anything else is just a 'pretender to the throne', for my money.
Seriously though, in no particular order
1. Clamps (You can never have enough.)
2. Rat tail files
3. Bench vise
4. Drill press vise (if you have a drill press)
5. Jig saw and various blades
6. Palm sander (I like the random orbital variety)
7. Analog or digital caliper for measuring limb thicknesses, accurately and quickly.
8. Sanding drum set (use them in a drill press or hand drill)
I haven't even built my first bow but I have been preparing for several months and I can already see which of my tools I will not be able to live without.
Hope that helps.
Take care,
Matt
