Most items on orders that include $50 or more will ship for free.
The exception is disposable cups and lids.
Disposable cups and lids will always include shipping as they are bulky commodity items.
We could not offer free shipping if we included sleeves of disposable cups and lids.
Starter Kits and Gift Packs always ship free, including the $39 ones, even if your order total is below $50.
This is noted on disposable cup and lid product pages.
(Of course, that the cups and lids that come in starter kits and gift packs are included in those packs, so those do ship free.)
Please contact us if you have further questions and thank you for understanding.
