Domestic Order Shipping Options - Most domestic orders may be shipped using UPS or USPS. Actual rates for online orders will vary depending on the shipping location.


All orders are shipped from Rocklin, CA.  Delivery dates will vary based on destination and selected shipping method.

Free Shipping Options - Free US domestic shipping promotions with minimum purchase requirements are available periodically.  Applicable free shipping options, if available, will be presented in the shopping cart at the time of processing.  The customer must select the option at checkout; shipping option will not be changed or refunded once the order is processed. USPS shipping is not available to orders containing LiPo or SLA batteries. Orders over $200 before tax will be shipped via UPS Ground.

USPS First-Class Mail is neither tracked, nor insured, and is not available to packages over 13 oz nor orders over $200. Shipping weight includes packaging. Customers accept full responsibility for any lost or damaged orders. These orders will not be replaced or refunded by Parallax.

Saturday Delivery - All online orders are delivered Monday through Friday, unless you call our Customer Service Department at (888) 512-1024 in advance to request a Next Day Air Saturday delivery for an extra charge (usually $20 plus the cost of a Next Day Air shipment).

Stock Availability and Back Orders - We take every effort to ensure adequate stock at Parallax Inc., but we periodically run out of products. If your order contains one or more backordered items, the entire order will be held until all items are in stock and can be shipped together. To ship in stock items immediately, and backordered items separately at a later date, you must call or email sales and specify that you would like to ship a partial order.

If you request backordered items to be shipped separately, you will be charged an additional shipping fee when those items are shipped to you. Your original shipping charges will be adjusted downward (based on weight and dimensions) to reflect the cost of only the items sent. The backorder shipments will be shipped the same method unless you contact us at to specify another shipping method.

Batteries - Orders containing rechargeable lithium or sealed lead acid batteries will only be offered the UPS shipping option. Lithium and sealed lead acid batteries may not be shipped alone (without equipment) to certain countries.  Other shipping regulations may apply to orders that include large quantities of batteries, which may affect the final shipping charges for your order. (The US Postal Service will no longer ship items that contain lithium or sealed lead acid batteries to select domestic destinations, and to no international locations including APO and FPO addresses; therefore we are no longer shipping rechargeable items via air shipment such as USPS Priority Mail.) 

International Customers

International customers should consider using our distribution channels. Distributors provide reasonable prices as a result of consolidating their shipments, working with local customs offices, and using preferred freight carriers. This usually results in a savings for the international customer. Find a distributor.

Parallax is not responsible for any brokerage, customs fees, or country taxes. The actual value of all orders is indicated on the invoice, and restatements using lower values are not permitted. The cost of the order will be higher than if you use one of our distributors.

USPS First-Class Mail International is neither tracked, nor insured. Only allowed for orders up to $150 in value. Shipping weight includes packaging. Delivery usually takes 2-4 weeks, but can take 6 weeks or more. Delivery is made by the destination country's postal service. All duties and taxes for international shipments are the responsibility of the customer. Customer accepts full responsibility for any lost or damaged orders. These orders will not be replaced or refunded by Parallax.

Lithium Batteries - Orders containing lithium items will only be offered the UPS shipping option. Lithium batteries may not be shipped alone (without equipment) to certain countries.  Other shipping regulations may apply to orders that include large quantities of batteries, which may affect the final shipping charges for your order. (The US Postal Service will no longer ship items that contain lithium batteries to international locations including APO and FPO addresses; therefore we are no longer shipping lithium items via air shipment such as USPS Priority Mail.)
