Please read the following! This will answer most questions, and help eliminate misunderstandings.

These are USED tubes, not in individual or original boxes. Prices are per tube.  

 We are not wholesalers, and do not encourage best offers, or offer quantity discounts.

Shipping: We ship Monday through Friday, (except holidays, when the post office is closed) usually the day after receiving payment.

We use USPS exclusively. Packages are shipped by USPS First Class mail.

International shipping is by USPS First Class International. (up to four pounds)

You will receive an email when the shipping label is printed containing shipping details and tracking information, if Ebay & paypal have your current email address.

Tracking for International packages sometimes ends when it leaves the USA, and our postal system.  (Gradually, more locations are enabling tracking)

I have no way to find out where your package is, but be patient. Delays are usually at the customs department of the destination country. (if it left the USA, it already cleared our customs department) 

Shipping discounts will be automatically applied (when applicable) at checkout IF all purchases are paid at one time, with a single payment.
