Dew Drop Substitution

I saw these and fell in love with them. They are perfect for little flower centers or just that extra something on a card. But I'm cheap and haven't bought any yet. Then I was at Robert's yesterday (think Joanns with no fabric or a Michaels- you can buy them there too) and saw these in the wedding/flower arranging isle. It was $11.49 for a 1 pound bag. But I used a 40% off coupon. So for $6.90 I got a huge bag. They are all clear, but I think I can color them with re-inkers or Sharpies or something. And a few of them have air bubbles, but for that price, I could throw all the ones with imperfections away and still come out ahead. Is it wrong to get so excited over something so small?
