Aida, I agree with JessicaLam's recommendation of ULINE. I've been very pleased with the this company. If you'd like, sign up for their mailing list to get one of their catalogs. The prices are reasonable. They have every size shape box ; anything shipping related its there. Bubble wrap is very economical. For shops that sell many of one item its easier as you know what size boxes to order in advance. I will not use old shoe boxes or newspaper to wrap or ship my items, even though I sell mostly vintage! I think it is tacky and unprofessional. It is your shop's image. Discounts are offered for buying in bulk too. I recently ordered from the sale catalog and the prices were excellent. Delivered in 48 hrs. This company sells to businesses, both large and small. Hope this helps. Shipping and packaging costs can be a killer!
