Product Overview

How does it work?

Once you've subscribed to PhD Unlimited (details on how to do that below) you'll notice a new delivery option appear in the checkout for your next orders, called "Free Unlimited Next Day Delivery". All you have to do is select that option when you checkout - it will even be auto-selected in most cases. You'll then be sent your order as per the standard delivery timeframes for all of our Next Day Deliveries, shown below as a reminder.

Weekdays:Orders placed before 7pm will be delivered the next day - including on Saturdays (For example if you order at 6.45pm on a Tuesday, you'll receive your delivery on Wednesday). 
Orders after 7pm will be delivered the following day - Including on Sundays (For example if you order at 9pm on Friday, you'll receive your delivery on Sunday).

Weekends: Orders placed before 1.30pm will be delivered the next day - including Sundays (For example if you order at 12.15pm on a Saturday, you'll receive your delivery on Sunday).
Orders after 1.30pm will be delivered the following day (For example if you order at 3pm on Sunday, you'll receive your delivery on Tuesday).

Sounds great, how do I subscribe?

It couldn't be simpler - select the 'Add to Basket' button above and check out as normal. You will be prompted to create an account during checkout and free next day delivery will be automatically selected. 

Now that i've subscribed - How do I know how long I have left?

PhD Unlimited is valid for 12 months. Simply log into your account and you'll find a progress bar under the heading "PhD Unlimited" on your Account Dashboard. If you can't find it or are still unclear, our friendly customer service team are always on hand to help.

PhD products are affordable and nutritious I have used their products for many years



I think this has been a blessing. I order from PHD and get next day delivery. It’s already paid for for the rest of the year. So easy and what a great idea. Thanks PHD. If you order from here on a regular basis go for it. Easy and peace of mind.



Good delivery 👏 👍
