As long as you are exactly sure the style, size, and color before you order online then thats fine.
I ordered 7FAM on their site, knew my size and style but thought the color was more grey color but ended up something else. So had to return.
7FAM has some sales on their site right now, 7forallmankind.com, where jeans that were $19x.xx and now $11x.xx.
Also they charge brokerage fee/duties some where around $30-$40 cdn and of course shipping on top.
Otherwise, head down to macys or nordstrom and purchase since they often have sales, well mostly macys.
Good luck bud
