Buy any Sigma product at Sephora to get a free mini Sigma E25 Blending Brush and a makeup pouch.
There's no minimum spend to get the gifts, but shipping is only free on orders over $55, so I would recommend reaching that threshold.
The full length E25 Blending Brush sells for $23, so this is a neat little gift considering you can pick up a Sigma eyeliner for as low as $9 for example. However, if you aim to follow my advice and are willing to spend a minimum of $55, have a look at the following product or combinations:
* E55 Eye Shading Brush + F30 Large Powder Brush for $55
* Lipstick + Mascara $56
* Eye Shadow Palette - Nightlife for $59
* Eye Shadow Palette - Warm Neutrals $63
* F15 Duo Fibre Powder/Blush Brush + Powder Blush $63
I love free product offers, usually these give me an extra push to buy things I have been thinking of getting for a while. Like quality makeup and brushes... I have bought a few good brushes in the past and I absolutely love them. Time to give Sigma a try.
