Which would be... oh, yes: cheaper.
Just as much as Justin's earlier example. Battlefront released a supplement for US armored and armored infantry forces. Then they released a supplement for other US infantry forces, and (probably to reduce the publications SKUs by one), included the lists from the previous supplement. It did not change the lists or in any way invalide those in the previous supplement which one might have purchased. It in no way reduced or in any other way altered the value of the first supplement for those who had bought it. All it did was give extra value for those who had not bought it the first time, and were now buying the combined supplement. Yet Justin apparently felt hard done by, and says he tipped his FoW pram over as a result.
In your case, the proposal seemed to be that Battlefront's vehicles are extravagantly priced in the manner of GW boxed sets. Apart from most of Battlefront's *own* boxed sets providing a minor savings over purchasing the vehicles individually (as they usually come with stowage and transfers: yep, minor), I demonstrated that on any given day, you can get Battlefront tanks *cheaper* than the primary competition in the UK. Peter Pig rarely has sales (certainly not recently), and I've never seen Skytrex on sale, either through the Web site or at shows. Over here in the US, we're fortunate with the Old Glory Army and Old Glory 15s' near-continuous sale of Quality Castings. So neener, neener. But in the UK, there's no reason to suggest that Battlefront's toys are overpriced. They're not.
There are many things about Battlefront and the Flames of War rules that do not give me ecstatic joy: poor production control, poor customer service, some very dodgy figures now and then (more now than then, which is a disturbing trend). Folk can argue endlessly over the rules: whether IGOUGO is good or eeeevil, whether the absence of specific "opportunity" or reaction for is a fault, the variable ground scale. Those don't matter: virtually every rules issue that one critic will foam over can be found in some other WWII rules. For me, they do not give horribly unrealistic results when played by someone with a little military knowledge and knowledge of the period. Generally, I prefer IABSM. (For which, I might point out, a Peter Pig Sherman is still six quid, while a Battlefront one is five pounds, 85p...)
And there are aspects of the GW business model which Battlefront has adopted: not surprisingly, and quite successfully (which seems to be the root cause of much criticism). But these blanket statements that Battlefront is just a GW clone are way off the mark.
