Just want to make sure I am getting the greatest discount/the advertised discount, thank you!

Some of our partners may offer a discount. To find any available discounts, I suggest using google search. Please always ensure that any links you click on for a discount lead you to https://turbotax.intuit.com The current pricing on our website was correctly provided by @SForrestLO. 

Thank you-  I did check other discounts but this $30 for the deluxe is what appears on the turbotax.intuit.com site when I visit- just want to know if it's advertised as that why I am being charged $40 for a federal return:
