Investing app Acorns is offering to match your Found Money, if you earn $35 in September. Found Money is basically cash back that you earn by shopping at other merchants and it is invested into your Acorns account. This is effectively doubling the cash back rates that they offer.
Bonus rewards for Found Money Month are a limited time offer, and may only be earned on purchases made between 12:01 a.m. Pacific Time on September 1, 2017 and 11:59 p.m. Pacific Time on September 30, 2017. To be eligible for a bonus reward, you must earn at least $35 in Found Money rewards during the offer period. Bonus rewards are in the form of a purchase of investments in your Acorns portfolio, and will show as pending until the qualifying Found Money rewards have been processed into your account. This may take up to 120 days depending on the Found Money partner(s), and travel-related rewards may not process until you have completed your travel, journey, rental, or stay. You are only eligible for one (1) $35 bonus reward with respect to this promotion. Acorns reserves the right to restrict, revoke, or change this offer at any time.
A nice offer, with doubled cashback on up to $35 of Found Money. Just make sure you compare rates on Cashback Monitor or similar site, so you can get the best return.
