I like to have flowers around my house whenever I can. I try to pick up the $5 bunches at Wal-Mart, and Sam's Club when I am there. This week, the flowers start to go up in price due to Valentine's Day, but I managed to snag some perfectly pink tulips for $6.
To jazz them up a bit, I took some leftover red velvet ribbon from Christmas, and these glittery wire centerpieces that I snagged at Wal Mart's after Christmas sale for $0.50 a bunch.
Now I have a Valentine's Day centerpiece that cost less than $7! I just change the water every couple of days and trim the stems to keep them fresh, and they will last over a week through Valentine's Day.
