Stick to the budget or spend less?

[SureJan]

If you have a budget of £30 to spend on someone's Christmas present, but you manage to get the present on sale at £20 - would you get them an extra present with the £10 you've saved, so that you've truly spent the full £30 on them? Or would you leave it at spending just £20 knowing that they're getting £30 worth of stuff (saving yourself a tenner)?

I've used the wrong word, I mean agreed amount rather than budget.
I thought it was ok because I still got her exactly what she'd asked for, not like I got her a cheaper version of what she wanted.
But yeah, wrapping up the bloody delivery note & proving my CF-y was a massive error!
I'll make it up to her on her birthday in a few weeks & spend a tenner more on her gift for that!

I'd definitely spend the extra in your case, either give her the tenner or buy her lunch or something.

Seeing as you've been caught out I'd buy something else.

If you hadn't been then I would've just spent the £20 tbh.
