One good thing about being on a tight student budget is that it encourages a lot of creativity in the dates and other activities we do as well as gifts we give. One time we each had a few dollars to spend at the dollar store and were assigned various courses of a dinner to buy. We ended up with quite the array of funny dollar store food for dinner, which we enjoyed at the park! A few weeks ago we went to Whole Foods and took advantage of the many cheese samples they had out, ate some goat cheese/tomato/pesto pizza (SO yummy), and got a few ounces of cashew butter, almond butter, and pecan butter to try at home. Sometimes it ends up that we weren't able to arrange a babysitter, so we have stay-at-home dates, like this one:
My sister brought us back these dinosaur models from her mission in Taiwan and we had never put them together. So the other night Sam picked up a sampler or Taco Bell's dollar menu items and we enjoyed our food and then raced to assemble our awesome T-Rex models. (Thanks, Breanne!) Another time recently we had a candlelit dinner of waffles and enjoyed a documentary afterwards. Once we went to IKEA and had a little scavenger hunt where we tried to find random items on our lists.
I could go on, but the point is just that when you're determined to find good, inexpensive fun, the options are endless!
