I've had a few setbacks since I began living a more frugal lifestyle, and each time I've felt regret and guilt afterward. This past weekend I purchased a used bike, with some related accessories. This purchase was budgeted, and actually I spent less than I gave myself 'permission' for, but for some reason I still feel uncomfortable. This might be because I'm so unused to dropping more than $50 on anything these days.
Also, once the money started flowing (budgeted or not), it became much easier to whip out the debit card and make some purchases I normally wouldn't have. Here's an accounting of my expenditures last weekend, along with a notation indicating whether the purchase was included in my budget---or not.
Granted, looking at my expenditures in this way, I can see that the total is only slightly more than what I budgeted for my bike expenses. So, my budget is safe for now; however, had I not spent extra money on pretty flowers and a bike rack, I could have sent that extra money to debt repayment or emergency fund savings instead.
