Keep in mind that when using a credit card to pay a vendor via PayPal, you'll incur a 2.9% plus 30¢ fee per transaction. If you're using a credit card to pay via Venmo, you'll incur a 3% fee per payment.
However, if you're working on the minimum spend for the Chase Ink Preferred (CIP) ($5k in 3 months for both your husband and you!), Venmo is perfect because although you'll incur a 3% fee, Venmo payments "code" as "trvl, ship, adv, telecom" and earn 3x Ultimate Rewards points -- effectively negating Venmo's transaction fee. If you're not working on a minimum spend for a new card, the CIP should be your default card when paying through Venmo.*
As I've explained, 1 UR point = 1¢, so your 3x UR earnings on Venmo payments exactly negate its 3% fee. However, if you transfer your household's UR points to a CSR card (I'm guessing your husband's), and you're redeeming UR points for travel (like booking the
Disneyland Hotel) on the Chase UR travel portal, 1 UR point is worth 1.5¢. (If you redeem UR points on a CSP through the Chase portal, they're worth only 1.25¢).
*P.S. I wouldn't bother with PayPal if you're going to pay with the CIP. PayPal earns you only 1x points, whereas Venmo earns you 3x UR points when using CIP. If you're working on a minimum spend for any other card, I'm not aware of any difference in the way they code, and thus how many points or miles you earn. PayPal is more ubiquitous, but Venmo is popular among more social media savvy users. My dog sitter recently stopped taking credit cards and moved to Venmo. If you're paying your vendor some substantial amount of money, the least he can do is spend 15 minutes downloading PayPal or Venmo and setting it up for you to pay him. Funny thing is both apps are owned by PayPal.
