Hello @carlynn. How awesome you're going to save in HBD and take advantage of the 12% interest. Good choice.
I'm following the Weekly Chart you captured below. I already see a huge difference in my account. However, you can save whatever amount you're comfortable with. At any time I don't have the weekly amount of liquid available to save, I'll just save whatever I have. Hopefully I'll be able to catch up the next following week.
Good luck on your weekly savings.
Wow, this is a smart idea, thank you for this, I am sure going to keep this in mind.
