In-App Purchases: Amazing!
We love this!!! It removes the stress of hunting for filter sizes from store-to-store and ensures that I’m getting a product that works with the app. Having a variety of retailers to choose from is a bonus, but just Filtrete would suffice too (and probably help Filtrete preserve its retailer relationships too).
Here are a few suggestions to make this feature even better:
- Easy price comparisons
- Shipping costs are a hurdle; perhaps offer price breaks early on
- Make this feature more visible/prominent
- Consider volume purchases and associated discounts
- An auto-purchase/subscription feature
