Is working as a Purchasing Specialist a good entry level job for an Economics major?

I wouldn't be asking this question, but I am so hesitant because it is for a field that does not deal with what I want to do (business/finance). If i get this job, I'd be working for a electric plumbing supply company working as a purchasing specialist where I have to forecast how many goods we need to purchase based on past sales and such. Also I would have to make sure the company is getting the best, most competitive deal out there from their purchases. I might be overanalyzing this. Can someone please help? Thanks.
