Iâ€™m in marketing and I use a few different suppliers to get promotional material for our clients.
I was looking into bags, mugs, Frisbees, etc. for our OOT and found some of them have great prices. Especially when you order multiple quantities!
You can customize your order to have whatever you want on the items or you can order them plain and DIY.
If you do a Google search for promotional products in your home town you should come across a few!
Just a thought! Hope this helps!
