How to use a cash budget and buy items online?
Using a cash budget, say we save $100 for household items. Typically, we would withdraw $100 from the ATM, put it in an envelope, and then later, go to home depot or walmart or wherever and buy an item for $20. Now I want to buy one item from Amazon.com (or anywhere online). What is the best way to handle this? Do I go re-deposit the cash? Do I leave money in my bank account in case I need to buy something online? I'm looking for strategies to track that $100 and be able to buy items online.
