When looking for unique crafting supplies such as embellishments and organizing products, think and look outside the 'big box' and scrapbook specialty stores:
Office supply stores---great for organizing products at a great price, especially during 'back to school' sales. Also offers fun brads, paper clips and papers.
Home building supply stores--check out the tool tote aisle, you might find the perfect product to carry your supplies to a crop. Screws, nuts, bolts, colored wires, colored tapes make fun embellishments.
Grocery Stores---some stores actually have a paper crafting area of supplies. Watch for clearance sales.
Stock up stores---great prices on all kinds of office supplies, especially tape.
Overstock stores---some have big box store leftovers at a greatly reduced price, especially albums.
Second hand/thrift stores---great for all kinds of treasures, it's like a year round yard sale.
