第二，不断膨胀的投资模型。有些品牌原本投资仅需30万，却突然提升至80万，还要求加盟商频繁更新形象。蜜雪冰城曾将形象更新周期从3年调整为4年，核心就是避免加重加盟商的二次投资负担——过多的二次投资，相当于让加盟商重新开一次店。

Compared to the third-gen Polaroid Now Plus, my former retro pick, the Flip delivers clearer shots with fewer wasted photos, making the extra $50 worthwhile given that eight I-Type sheets are a spendy $18.99. The increased clarity can be attributed to several factors, including the Flip’s sonar autofocus and a four-lens hyperfocal system — which result in sharper, more focused images — along with its excellent flash. It’s the most powerful of any Polaroid camera, and while it can sometimes overexpose images, you can adjust exposure directly from the camera or app. The Scene Analysis feature also helps by warning if a shot is likely to be over- or underexposed, or if you’re too close to your subject. In my experience, the warnings didn’t always prevent overexposure, but they did leave me with shots that looked less blown than those from the Now Plus.
