Download and sign up to Mercari for a free $2 credit. You can download it here and get a free $2 credit when you sign up.
When signing up make sure you enter referral code BHDYNX to get your $2 credit (it might be case sensitive). After that you can get your code and every friend you refer you can get an additional $2.
Your referrals don’t have to make a purchase for you to earn the $2.
After you sign up check out my favorite seller. She offers light switch and outlet covers in tons of different designs for $5-$7. So if you sign up and refer a few people you can easily get something for free.
