Am I being really dim? Re boden 20% off offer

[CareBearWithFangs]

I have an email from Boden offering 20% off until Wednesday, so far so lovely. But I can't find the offer code on the email. Has anyone else got this email?

I thought maybe it might take 20% off at checkout but it's not doing that either?

Is it just me being dim? Help!

Have you clicked through from the email?
Are the prices on the website already reduced?

I've managed to work it out. I clicked on the link to items that aren't included in the offer and there was a banner on that web page saying 20% off and that banner took me to the code, hooray! Saving nearly £20

I had a postcard last week with a 20% offer Sunday-Wednesday and free delivery. The code on the postcard didn't work and I only seemed to get free delivery but no discount, so I had a quick google and found a 20% off code that worked. The code was G845.
