All of my items are made by hand once ordered. Most items can be changed/altered/personalized to some extent. A majority of items can just be added to your cart and you add a note in the 'notes to GlassPoppies' section during checkout specifying color, wording, gift notes, etc.
I offer tier pricing on identical items. Items themselves need to be the same but personalization can be different to qualify for the discount.
3-5 identical items = 15% off
6-9 identical items = 20% off
10+ identical items = 25% off
