Free Budget Shipping
Many items at NothingButSavings.com offer FREE Budget Shipping. Plus, as with many of our competitors which do offer free shipping, we don't ask you to spend a specified amount in order to qualify for FREE Budget Shipping.
How do I qualify for Free Budget Shipping?
1. Add the item(s) that qualifies for FREE Budget Shipping to your order's shopping cart.
2. If a product has our "Free Shipping" tag that item will qualify for FREE Buget Shipping regardless of its price.
3. Proceed to checkout and select Budget Shipping as your shipping option (items will take an additional 7-10 business days to ship).
4. Ship your item(s) to a valid U.S. address.
5. Then, complete your order. It's that simple!
6. FREE Budget Shipping excludes certain oversized and/or overweight items, and those products that do not include this tag.
Some items may be excluded:
If certain items in your shopping cart are not eligible for Budet Shipping then buedget Shipping will not be available and thus the offer for Free Budget Shipping will not apply.
Free Budget Shipping is not available for International orders.
