if you don't use cash a lot, think about starting a virtual piggy bank. every time you make a transaction from your card/bank, however many cents is needed to get to the next dollar you can put in your savings account. i reckon that would add up pretty fast. if you have transfer limits, maybe just keep a note with every amount for a month and then do one transfer at the end of the month.
idk, just a thought i had because at the end of the year when i gather all my coins together, i usually have like $100+. it's fun to use on a bigger purchase. i used to take all my friends out to eat for Christmas with it.
@LukeAlmighty people say girl math to everything these days. i thought it was supposed to be like, getting "deals" on things that require you to spend more money. like 2 loaves of bread for $4, but one loaf of bread for $2.50. such a good deal! but then one loaf goes bad before you can even finish it.
