There is a GOOD sale going on at Rue LA La on Built NY products. You can get laptop neoprene sleeves for as low as $15.90. There are also laptop slings for the same price, camera cases for as low as $5.90 and more. I believe you only have until 12/31 to use the free $10 sign up credit previously available (that offer is now expired).
Even without the credit this is very cheap for these sleeves that come in some nice designs. And don’t forget that when you pay the $9.95 shipping cost that entitles to free shipping on any purchase at Rue La la for the next 30 days.
