Hi yes 150 unique visitors. the website is allthebesthampers.co.uk.
Any advice would be appreciated.
Thanks
Okay thanks. I'm not sure about your industry but generally speaking ecommerce conversion rates are about 1%-5% so you should have an order or two depending on where the traffic is coming from. Do you have any further information on that? Do you know what kind of search terms are bringing people to the site or if there is traffic from other websites maybe? Do you know exactly at what point in the process people are abandoning? Any in particular?
I have had a look at your cart process and it is pretty long winded. The whole checkout process to complete the order is 8 pages!! For comparison our site takes 4 pages to complete the order. I appreciate there is some further information required for your products but I think it's an issue you need to address.
Some additional points:
There is a lot of distracting text above the very first page of the order basket. Assuming you can customise cart layout I'd consider deleting most of it and maybe keeping the following:
You can enter different delivery addresses for multiple hampers at a later date.
**Please note Saturday delivery is only available in UK Mainland**
But move it to the bottom of the cart.
When you get an estimate for shipping you have UK Mainland but also a separate listing for Scotland / Highlands at a cost of £12.95. I'm sure this is correct of Scottish Highlands but it reads like the cost for ALL of Scotland. Surely this is not the case and this would fall under UK Mainland? If so, amend it to say Scottish Highlands instead of Scotland / Highlands as it will put Scottish customers off.
I would consider taking out the section about local hospitals. Sure it is good to know if this is sending you customers but it's just another distraction in the cart process where it might not be relevant.
An additional distraction I noticed was the cookies notice. As far as I'm aware the guidelines on this were softened and you just need to make customers aware about the use of cookies in your terms and conditions. I would look in to this and amend it.
Finally, remember you will ALWAYS get abandoned carts. Often it is just a customer checking the shipping price or they have simply changed their mind. You could experiment with making the Delivery details page more prominent to see if that helps.
I hope this helps a bit. Sorry if I've created a load of abandoned carts testing this.

On that note, none of the 11 abandoned carts were you were they? Just a thought.
Maybe look in to seeing if you can implement SagePay Direct as it means you can process payment on-site rather than having to go off to the SagePay payment pages.
Let me know if you want any clarification on anything if it doesn't seem to make sense.
Edit: PS Not really related to the cart (but possibly) do you have any business to business sales or are you mainly selling to consumers? If so, I'd remove the ex VAT prices and only show including VAT. It can confuse some people and its unnecessary to have ex VAT pricing on a consumer targeted site.
