We have are car loan throgh WF and as long as we don't miss a payment they leave us alone but miss a payment and for months they will drive you nuts. I pay mine through internet banking right to the account, the first time the payment fell on a Sunday, I paid it the Saturday before (computer was set to remind me the day before it was due), but on Monday they called to find the payment, gave the reference # and thought that was it. Nope, they called the next day and the following day - which is when they would have received it due to the the weekend - usually they get it the next day or day after that. Then the following payment is coming up they called me a week before to give me a "friendly" reminder and then called three days before and the day before. They did that for 3 months, till I told them that it can be construde as harassment according to my lawyer as I receive written notice monthly of the upcoming bill date - never talked to a lawyer but they don't know that but it made them back off.
Banking wise, I think we have all become to dependant on our little pieces of plastic the bank assigns us (bank and credit cards).
I try to always have cash on me for the small purchases and if I don't have it, I don't buy. I personally can't explain to myself why I would use my bank card to pay for anything under $5-10. - especially since the smaller stores around here charge an extra fee. Plus it makes it so much easier to go over budget and put us in the hole at the end of the month as those little purchases add up. I go to the bank once a week, take out the budgeted grocery money and take out a little extra for the incase moments during the week like DH picking up milk on the way home, also to give some to DH for coffee while he works. Any grocery money left, goes into a "jar". During the month if I need to buy extra groceries or pay for a surprise trip/project at school I have the extra and at the end of the month if there is any left, I take it to a seperate bank and put it in a savings account. Also I'm the only one with a bank card to the account. This way we can keep better track. We found with both of us having access we would forget to tell the other if we spent any (Christmas was the worsest) and since I keep the "books" and do the shopping we thought it made better sense. We are trying to get our credit cards to zero balance and have put all but one in the freezer as right now I use it to pay for gas for the car then go home and pay it off that night or in the morning before I leave. So every month I work towards paying down the card rather than my newest purchases. My accountant prefers I do it this way rather than taking a chance of loosing the receipts during the year - plus cheaper at income tax time when she does our taxes as she charges extra to go through receipts.
