I'm asking because I'm wondering how the seller would even know whether we bought a single license or an extended license? I'm on the fence on buying some PSD files and the commercial license is $10 while the "extended developer license" is $20. Both products are the same, no watermarks with the commercial license, limited use, etc. I know the difference between both is that with the commercial license only you could use it. The extended version could be used by your clients, etc. The big question is would they know if I bought a commercial license and then used it for my clients as well? It kind of sounds like just asking for more money since this isn't like a software or anything like that. Just some PSD files which i'll customize myself to fit my niche, then give them away as a bonus for a product im working on (not the original files, but ones I've redesigned myself) What are your thoughts on this? Do you guys always buy the extended license? Thanks.
