False Advertising

FNB advertise their smart devices to be sold \INTEREST FREE""; they currently have a 40 FHD Samsung tv advertised + Bluray player for R299 per month x 24 months which equates to R7176 for the 2 years; after checking on price check; the tv sells from R4700 - R5500 and blu ray sells from R1000 - R1400; even taking the highest end of those prices equates to R6900; R276 below FNBs advertised interest free price; when I questioned the consultant; she explained that it retails for R9000 hence FNBs over is great. can some one please explain what I am missing here. if you take the bottom end of that pricing; the package equates to R5700;this is from a reputable store with the same warranty."""
