Best option is when west marine has them on sale along with a lowrance mail in rebate. Have bass pro price match west marines sale price with the 10% discount code on top of that. Than pay using bass pro gift cards that you bought online for 13% off retail. So $649 retail. West marines sales are norm $150 off when they have them that would bring it to $500 than 10% off so $450 then bass pro gift cards brings it to $391 and than $100 rebate they norm have at same time as west marine sale brings it to a grand total of $330 including tax for a brand new HDS 5 gen 2. Oh and if you sign up for there credit card at same time they norm will give you another $100 off so if your lucky you could get it for $230!! If following lowrances pattern there next rebate sale should be this summer when this occurs if you want to wait. By the way this is how I got my HDS 7 except I didn't get the credit card, found out about that after
