USPS First Class Shipping

Available for: orders less than 13 ounces. 

Choose this option if: USPS First Class is for small orders of small items. Maybe you realized you’re out of a specific wick size or simply MUST sample the newest CandleScience scents. 

Delivery details: Saturday delivery available. Most First Class orders arrive within 3-5 days, but note that USPS does not guarantee transit times. 

USPS Priority Shipping

Available for: orders less than 70 pounds. 

Choose this option if: you need your order fast. Most packages shipped Priority Mail arrive within 2-3 days. Saturday delivery.

Delivery details: Saturday delivery. This is a good choice if your order is too large for Flat Rate Regional, but you still want the benefits of USPS shipping like detailed tracking info. Most orders arrive within 2-3 days, but note that USPS does not guarantee transit times

General Tips:

  • Plan your orders carefully! Big, heavy items like cases of wax and containers are most cost-effective shipped in bulk, so grouping those orders together as much as possible is best.
  • Fragrance oils with a flashpoint of 141°F or less cannot be shipped USPS and must go UPS Ground, which can make shipping these fragrances more costly than usual. Luckily, our entire fragrance line is now shippable by air!
  • Cases of wax ship in their own box and additional items will go into a separate box—even something as small as a few 1oz. fragrance oil bottles or a bag of wicks. Consider splitting those shipments into two separate orders and choosing UPS Ground for the wax and USPS for the remainder.

That’s all for now! We hope this cheat sheet helps, and stay tuned for more shipping tips and advice.
