Mis selling?

[BoomBoomZoomies]

I ordered a 'bundle' online from reputable company. The bundle was a good deal and I use all the products so placed an order.
The company has now posted that they made a mistake. The price was wrong and they've now increased the price.
They will honour those that have already ordered BUT will be removing one of the items.
Surely this isn't legal? I have the original photo and list of what was included and the original price
Do they have to hour original price and order contents?

I've noticed some other customers online are now complaining about the offer so will see if the company reply

According to CAB it seems the answer is it depends whether you have a contract yet. Which country is the seller based in? There's a legal section on here which might give a better answer.

Shopping online
Your legal rights depend on something fairly tricky in the law: whether or not you have a ‘contract’.
Depending on the company’s terms and conditions, you’ll have legal rights (and a contract) either:

once you’ve paid for the item

once they’ve sent it to you

You’ll need to find the company’s terms and conditions to find out where you stand. Contact the Citizens Advice consumer service if you need help. It may be too tricky to work out yourself.

Depends what's in the terms and conditions. I've had the same happen before and the company cancelled the order and issued a refund.

Thanks will see if I can find their T&C
