Backpack credit is a referral bonus which can be earned/shared by the referral link provided in "Backpack Credits" tab from the top menu bar. If you sign up at Backpack from a referral link of one of your friend who's a fellow Backpacker, you'll instantly receive 500 bonus Backpack credits.
How does it work?
When you invite a friend with your referral link to sign up at Backpack, you get 2,000 pending credits, which you can check on your “Backpack credits” page. After your referred friend makes his first purchase at Backpack you'll avail 500 credits and after they travel with Backpack carrying items for Bangladeshi shoppers, you'll avail the remaining 1,500 credits from that pending 2,000 credits.
How to use Backpack credit?
You can use this amount as a discount to shop at the Backpack. Once you take a credit applicable item to checkout, these bonus credits will get applied to a certain percentage to pay for the item price.
