I can confirm with you that the $20 off $40 purchase with Visa Checkout(code 179908, ends 4/10) can stack with the AMEX $10 cash back on $30 HSN.com purchase!

I just placed an order for the Artis Elite Palm Brush. It’s on sale for $50, regular price is $65. Shipping is free. This is a good deal even without the $10 AMEX cash back! There are also a few other Artis items on sale.

My actual cost is $50 – $20 Visa Checkout – $10 AMEX cash back = $20 + tax + free shipping!

I made my mind up to purchase this brush after I watched this video on the official Artis site! I am a bit impressed how effortlessly the model applying the makeup with this brush.

I received the $10 cash back email confirmation almost instantly after I placed order.
