OK, I bit the bullet for you guys and joined Boxed. Here’s what I found:
When you use a referral link, you get a message that says "You have $15 to use towards your first Boxed order (must be $60 or more). Code automatically applied to your cart. Offer may not be combined with other offers, promotions or discounts and offer not valid on Boxed Hotels.
So that was interesting info… I wasn’t aware of the $60 minimum for using the $15 referral credit, and I’m now not sure if it will stack with the SB offer. Both offers are only valid on yoyr first order. I placed an order anyway to see what happens since I found some things I wanted at a pretty good price before the 25% discount (and a steal if I get the $20 SB credit).
If you decide to risk seeing if they stack, click your referral link first to apply that offer to your account (it will prompt you to create an account)… then close that tab and enter Boxed through SB (and place all items in your cart and checkout in the same SB tab).
You get free shipping on your first order if you meet the order minimum of $19.99. After that, all orders over $49 ship free, otherwise shipping is $6.99.
You can choose up to 4 free samples with every order: https://www.boxed.com/samples
You get 1% cash back on every order and there are no membership fees.
Orders arrive in 1-3 days.
FWIW: When I signed up the welcome email included a code for 10% off my first order, but I didn’t use it because I didn’t want to push my luck and potentially lose the $20 SB CB since I’m already trying to stack it with the $15 referral credit.
HTH!
