A list of where I get a few specific things.

http://www.framingsupplies.com   ( I get my ATG gun tape here) 908 Gold 1/4 inch.  This is the cheapest place I have found it.

http://www.calendar-case.com/index.php  (This is where I get my calendar cases for my unmounted stamps.)  No CD ring in it and they are good quality.  Cheaper than anywhere I have found.

I shop EBAY a lot for most of my Cricut cartridges with free shipping, unless I can find a awesome deal somewhere else.

http://www.orientaltrading.com/  is where I get many of my brads and bling.  Great prices and shipping isn't bad.
This is where I purchased my EZ Mount Foam. http://www.flipflopsandrosesdesigns.com/  Very Very reasonable.        
For most of my paper I shop at Joann Fabric.  I have some Stampin Up paper.

If you want to know anything else, leave me a comment.

Have a wonderful Sunday.  Happy Scrapping.
