I would google cake supply store where you live. If none, then go online to see who has the better deal. Anyways check on the shipping and what their return policy is. Some local store don't give refunds or exchanges. Good luck!
Where in the US are you moving to? Some great suppliers online are Globalsugarart.com, intotheoven.com, cakesbysam.com, and pattycakes.com. Their are others out there too. Im sure you will find that a lot of the local cake supply stores wont have everything you need and you will have to rely on online buying, unless your lucky!! I unfortunately dont have any suppliers that arent over and hour away so I buy most of my stuff online or make it myself.
Oh, and welcome to the US!!
hi welcome back to the state! I asked a similiar question a few weeks back. I don't know how to get you there for sure but here's a try. If you search in forums, the topic was Cake decorating and the subject was: I admit I'm a cheapskate. Also maybe you could click on my profile and then go to all of my posts and find it that way. There were a lot of really nice posts of places to shop online. good luck! 
I buy most of my supplies from www.intotheoven.com they ship very fast. I get my supplies within two days from the date I order.
