Neopets: Job Coupons? HELP!!?

I have 102,000 NP. This is including money in bank and on hand. I want to buy a job coupon, but I'm a bit confused.





-Are coupons only usable once?


-Should I spend all my NP on a coupon?


-Which is the best coupon for me and why?


-Where can I find coupons at the cheapest price??





Sorry to squeeze so many questions into one!!





Thanks in advance.Neopets: Job Coupons? HELP!!?
