Order Policy

We offer free expedited shipping with DHL on any order over $75. The $75 total is after discounts, before tax or shipping charges. Orders under $75 are eligible for expedited DHL service for a flat rate of $4.99.
We also offer UPS Ground shipping on all orders for a flat rate of $7.99, and UPS 2-Day Air shipping on all orders at a rate that varies based on shipment weight and destination.

All orders ship in an unassuming, unbranded brown box, including our return address on the label.

There are two components to how long it takes between placing an order and delivery: order processing and transit. Please allow 24-48 hours for order processing. Transit times vary based on which shipping method you choose, and those date ranges are visible at checkout.

420 Science supports debit and credit cards from Visa, MasterCard, American Express, and Discover. We also accept payment via Sezzle, a platform that enables paying in interest-free installments.

We are unable to modify an order once it has been placed. However, you can submit an address change or cancellation request if you haven’t received a shipping confirmation. Simply reply to your order confirmation email or send an email to help@420science.com.
Please be mindful that we cannot update a shipping address or cancel an order once the order has been processed to ship. If we’re unable to cancel your order, we’re happy to help you start a return.
Please note: an address change or cancellation request is only guaranteed once an agent confirms your request has been processed.
We are unable to change billing information. If your order has already been paid for and you need to switch payment methods, we can only refund the original payment method and cancel the order. We cannot transfer payment between payment methods or refund any payment method besides the card initially used.

In the event you receive a damaged, defective, or incorrect item, we will replace it. You have seven days from delivery to file a claim. Send an email including your order number and a photo of the item to help@420science.com.
Please do not use the item or throw anything away until you speak with a customer experience representative. We may request you return the product.
If an item is missing from your order upon arrival or you haven’t received a package marked as delivered, please get in touch with help@420science.com. Missing items and packages must be reported within seven days.
If the shipping carrier (FedEx) provides sufficient Proof of Delivery, we will not offer a replacement for an undelivered package. We will assume that the Proof of Delivery is accurate, the package was delivered, and theft occurred between delivery and when you checked for the package.

You can initiate a return on unused items within 15 days of delivery for store credit with free return shipping or a refund to your original payment method for a $6.99 shipping fee. Items must be returned in like-new condition in the original packaging and as close to how you received them as possible. Due to Federal law, we will not accept any returned item that has been used. You can start a return here.

High demand occasionally causes certain items to sell out. If this happens with a product you’ve ordered, we’ll notify you by email. If the item won’t be restocked, we’ll remove the product from the order and issue a refund.
