As a former rep for Sally Foster here in Orlando Florida, I can tell you that it really comes down to what do you want for your school. It is up to the sales rep to help you with making your sales a success, and doing this actually begins at the time you sign a contract.
Keep in mind that you must feel comfortable with the sales rep. Ask for a proposal with those things that are importatant to you. For example confirme delivery date, help with printing of letters, extra prizes, live kickoff, extra percentage for sales over a specific net amount.
As far as product is concerned Sally Foster has the best paper, but not enough gift items, Jaxco has plenty but can they provide the service you want?, and Innisbrooke is usually 12% higher than all other companies.....You can do the math on all catalogs....Most of all remember you want to make the most with the least amount of headaches.
