Frequently Asked Questions

How are US orders shipped?

You can select Federal Express (FedEx), United Parcel Service (UPS), or United States Postal Service (USPS) shipping at checkout. We endeavor to ship all UPS and FEDEX orders received before 2pm EST the same day Monday through Friday based on supply. USPS orders are shipped the next day after you place the order Monday through Friday. Depending on your distance from Florida, Ground UPS, FEDEX and USPS delivers within 3-10 business days.

I need delivery tomorrow. Can you ship overnight?

When overnight shipping via Federal Express (FedEx) or United Parcel Service (UPS) is requested we endeavor to ship these orders the same day based on supply. In the event we cannot fulfill an overnight shipping request we will contact you to arrange for alternate methods of shipping. Select next day service in the checkout process and we will work to satisfy your request.

How are International orders shipped?

We ship anywhere in the world our shippers operate. Shipping options will be listed at checkout. All applicable duties, tariffs, taxes and brokerage fees will be the customers responsibility.

IMPORTANT: USPS does not offer tracking beyond the US border for USPS International Shipping. If you select USPS International Shipping, we cannot guarantee delivery after the shipment leaves the United States. Because of the high costs of UPS or FedEx shipping, many of our international customers use package forwarding companies. Learn more here.

How do I track my order?

We will email you a UPS or FEDEX tracking number the same day we ship your order. If you haven't received the email within 2 business days of ordering, send us an e-mail and we'll track it down for you.

Do you accept PO's?

We will e-mail a Sales Order back to you with total cost and instructions to complete payment.

Can I pay by check/MO/wire transfer/Net30 or use another carrier?

Most businesses, wholesale and international business customers who place an order by PO will be asked to pre-pay their initial order by credit card, check, money order, or wire transfer. Payment terms are reserved for select customers with who we have established a prior business relationship with. Please email to request a credit application.

Can I use my own FedEx or UPS account to pay for shipping?

If you wish to use your own carrier, include the carrier name and account number on your PO.

Why doesn't PayPal show the shipping charges?

When you select the option to pay via PayPal, it only shows the item total, not the final billing total. Note the instructions on the bottom of the PayPal payment page: "click continue to return to to complete your order.Clicking Continue in Paypal does not complete your order. When you click continue, you are returned to the checkout cart, where you can select shipping options, add any coupon codes, then complete the order (or cancel). Shipping costs will be added to your Paypal total automatically.
