Just a warning. Chase is trying to put a stop to manufactured spending. So be careful how you are doing it. This change is going into effect at the end of the month....
Cash-like transactions will be treated as cash advances. Cash-like transactions include, but are not limited to, the following transactions to the extent they are accepted:
purchasing travelers checks, foreign currency, money orders, wire transfers, cryptocurrency, other similar digital or virtual currency and other similar transactions;
purchasing lottery tickets, casino gaming chips, race track wagers, and similar offline and online betting transactions;
person-to-person money transfers and account-funding transactions that transfer currency; and
making a payment using a third party service including bill payment transactions not made directly with the merchant or their service provider.
