50SCORE
The Fitbit Surge Large Super Watch is currently on special by itself for $278.10 (Was $287), it can be used in conjunction with the $20 off promo to get the price down for $258.10.
However by spending another $22 you can get a further $30 off - I have added the Dick Smith Portable Black Speaker which is $24.98 (usually $39.98) to bring the total up to $303.08 - as it's a $300+ spend you can use the $50 off coupon to make the total $253.08. You are basically getting the Fitbit Surge Large Super watch for a further $5 off and getting a free portable speaker valued at $40 - in addition to the initial item special ($7.90 off). Red Speaker also available
The cheapest price for this Fitbit was $254.15 so you are beating this and getting a free $39 speaker.
I have used the portable speaker as a good example, you can use any item that is $21.90 or more to bring the total over $300 and then adding the 50SCORE code. You may like to add some batteries, USB drives or other handy items to get to the $300 total.
