Hey! hello again!
I noticed that Limiting your pledge is a feature not everyone knew about, so here's a little info about it!
First of all, you can go to "pending pledges > completed pledges > edit current pledge"
in your patreon menu, or click this link: https://www.patreon.com/bePatronConfirm?edit=1&u=291465 to do so.
There, you should see this option:

If you click "optional: set a monthly max ..." you'll be able to decide How many times you'll get charged monthly!
This means you can access all the rewards, without being charged more than what you decide. Works like magic!
Take this into account when pledging or editing your pledge so you don't get charged more than you want!
For example, if you pledge $15, you might want to support only once or twice every month, so if I deliver 4 rewards you'd be charged only the first $15 instead of $60
!
Obviously it depends on how much you'd want to spend. If your pledge $1, maybe you'd want to support 4 times a month, for a total of $4 !
