Anyway... apologies for what was a long intro...
Just as aside (I know, I'm making it even longer!!), I think that breakfast in bed and a hand made card would be utterly perfect on Mother's Day (especially if a long lie is thrown in the mix!), but if you do want to buy something, then here are some ideas for gifts.
Personalised travel mug from Snapdragon, £15
I was sent this fantastic travel mug from Snapdragon...
This would make the most perfect Mother's Day gift, and I think it's great value for money for a truly unique gift. The mug can be personalised in three ways... the hot drink, the name and the alcoholic drink can all be chosen specifically to suit the recipient.
There are also loads of other ideas for Mother's Day gifts at Snapdragon, such as handbag mirrors with personalised embroidered pouches (from £8), Mother's Day quote mugs (£15) and personalised notebooks (£6.50).
Bracelet by Lily Belle, £49
There are some absolutely gorgeous personalised jewelry items over at Not On the High Street, such as this nude leather and rose gold wrap bracelet from Lily Belle.
Personalised Family Illustration by PrintableWallStory on etsy, from approx £40
I've seen a number of illustrated family prints on the internet and I think this would be such a thoughtful gift for Mother's Day.
If you are looking for some more ideas, then there's also my Christmas Gift Guide for the ladies which has some suggestions that would also work for Mother's Day... perfume, make-up etc.
