Browsing on the US QVC site and noticed these options for their ADs:
Note: Once the first item in your Auto-Delivery plan has shipped, you can make changes to future shipments. Some restrictions may apply for certain plans and at certain stages in the shipping process.
You can make changes to the following:
Order Quantity: Increase or decrease the quantity for your plan.
Edit Color/Size/Flavor/Scent: Select a new color, size, flavor, or scent, if applicable.
Edit Ship-to Address: Select from your address book, or enter a new one to send a shipment as a gift. (To edit your Billing Address, visit "My Account.")
Edit Payment Information: Add a new credit card, choose a different card, update an expiration date, or change payment method.
Frequency: Select a new shipping frequency from the available options in the drop-down list. A new shipment schedule will automatically be established for all future shipments. (Some plans don't allow the frequency between shipments to be modified or may limit the extent of changes.)
Next Shipment Date: If a calendar is visible, the "Next Shipment Date" may be changed. Dates in black are available, while those in gray are not. Use the arrows in the top corner of the calendar to switch months. Click on the date you'd like your next shipment sent (the calendar will automatically close). Some plans don't allow calendar date changes or may limit the extent of changes.
Shipping Method: Select a new shipping method from the drop-down list.
Skip Shipment: Cancel a particular shipment but still remain enrolled in the Auto-Delivery plan.
Cancel All Future Shipments: Click this link if you'd like to cancel a plan and all its future shipments. (To only skip a particular shipment, use the "Skip Shipment" option detailed above.) Once you've canceled your plan, you may see a "Reinstate Auto-Delivery Plan" link. Click this to re-enroll and begin receiving shipments again at your original order price. This link will remain visible and available for a limited time.
My question would be, why does the US get so much more flexibility whereas Q UK is stuck in the dark ages?
