in which stores in USA can i find a suitable box to ship a racket....i mean where do you guy get you box?
Shoes are quite durable so basically any box will do, just add some bubble wrap or similar. Any stationary shop should have it or if you ship with USPS Priority Mail, they will give you boxes for free, here's the link: http://shop.usps.com/cgi-bin/vsbv/postal_store_non_ssl/display_products/productCategory.jsp?prodCat=/Shipping+Supplies/Priority+Mail
