We decided that it would be nice to have flowers in the house this year, as it's been a rough couple of months and we wanted something to look forward to and to brighten up the house. For $65 Costco delivered 50 roses (assortment of white, pink, and red), which I turned into several bouquets. They arrived on the 10th and are still going strong, and we've greatly enjoyed them. Most years we don't do flowers, but this year it was money well spent.
As for "gifts", $10.50 bought 3 Tony's Chocolonely slave-free chocolate bars (on sale), one for each of us here at home. The away kid got a hand knit hat with a thick brim to cover frozen ears, and I sent it in a box of things that needed to be sent anyway. I was lazy and bought 3 cards at Trader Joe's for 99¢ each, but DH printed my valentine at home. Valentine's Day is always celebrated as a family holiday in our home and will continue to be so until the young adults make homes of their own.
