East End Arces: $10 Credit for Signup, $10 Credit for Referrals, Promotional Items Under $10+ Free Shipping!
You'll get 10,000 credits ($10) for signing up, plus another 10,000 for every referral. If you check their Promo link--which you have to Like their Facebook page to view--they have items under $10 with free shipping every day or so.
Their new promo for today is a packet of Black Eyed Susan's for $3.99 with free shipping. That takes 4,000 of the original 10,000 credits for signup, so I still have 6,000 left for something later!
Go try it out! It's a nice looking site and it's mostly for flowers. Enjoy!
