Usually .COM at HostGator is $12.95. When registering, using the SPRING2018 coupon, you pay $4.99/domain only. I have checked, register to dozens of domain names still receive preferential price.
*** Payment can be made by both PayPal and Visa/Master.
The next year renewal is $15/year/domain – quite high so you should only register and wait 60 days, then find another provider to transfer. Domains at HostGator are easy to manage, transfer quickly so you can rest assured.
Wishing all a happy weekend!
