I love Bourjois Flower Perfection Primer but the tub is too small! What else could I use?

[SeptemberFear]

Just that, really! I absolutely love this product but it only comes in a weeny 7ml tub that just doesn't last at all. I know it's only a tenner but I'd be happy to pay a bit more for something that isn't going to run out in a matter of days.

I love the lightness and mousse-y texture, it goes on beautifully and really helps with makeup application etc. Has anyone got any recommendations for a very similar product that will last me more than a week?
