By law she has to allow people to return the kit if they change their mind, because they have not seen it in person before purchasing. This below is from Citizens Advice Bureau.
If you bought the item online, over the phone or by mail order
You automatically get a 14-day ‘cooling-off period’ when you buy something you haven’t seen in person - unless it’s bespoke or made to measure.
The cooling-off period starts the day after you receive your order, and there doesn’t need to be anything wrong with the item for you to get a refund.
You won’t get a cooling-off period when you buy:
- something that deteriorates quickly - like flowers or food
- an item that was personalised or custom-made for you
- anything from a private individual rather than a business
- a CD, DVD or software, if you break the seal on the wrapping
If you paid for standard delivery when you bought something, the seller has to refund this if you return it. If you chose a more expensive delivery option, you'll have to pay the difference.
Use your cooling-off period
You need to tell the seller you don’t want the item within 14 days of receiving it. Once you’ve told the seller, you’ve got another 14 days to actually send the item back.
You can
use our template letter to let the seller know you’re cancelling. Keep a copy so you’ve got proof you sent it.
You could also phone - but make sure you make a note of who you speak to and what was agreed. It’s a good idea to follow up with a letter or email.
Sellers must give you certain information when you buy something without seeing it in person. This includes their business address and phone number, and details of your right to cancel. If you didn’t get this in writing (they’re allowed to send it by email) then your cooling off period is increased even further, to a year and 14 days.
14 days is the absolute minimum cooling-off period that a seller must give you. Make sure you check the terms and conditions in case they’ve given you more time to change your mind - many choose to do so.
