🚚 Shipping & Delivery

💌 How Much Is Shipping?

We keep it simple and speedy:

Australia: $10 flat rate with Australia Post or trusted local couriers

Everywhere else: Is calculated at checkout based on your location (because your booty deserves premium delivery)

⏳ When Will My Order Arrive?

We hustle hard to get your order out fast:

Within Australia: Usually lands in 3–5 business days

International: Up to 14 days depending on where you are in the world

Heads up: Global shipping’s still a little funky post-pandemic, so a few delays may pop up here and there. We appreciate your patience (and your excellent taste in underwear).

📦 Will I Get a Tracking Number?

You bet. As soon as your order ships, we’ll ping your inbox with tracking info.

Didn’t get it? Hit us up at support@tweakmeonline.com.

Pro tip: All parcels come with authority to leave—so if you’ve got specific drop-off instructions, let us know at checkout.

No PO Boxes, please. Make sure your delivery address is attended during business hours.

🚛 Which Courier Do You Use?

Australia: Australia Post or a local courier service

International: We choose the best based on your location.

💸 Will I Pay Extra Taxes or Duties?

If you’re shopping from outside Australia, local customs fees, import duties, and taxes may apply. These aren’t charged by us, so check with your local customs office if you're unsure.

Any questions? Don’t hesitate—drop us a line at support@tweakmeonline.com.

Your order’s in good hands—and soon, your cheeks will be too. 😉
