Hi Christopher,
Our pricing is based on our purchase prices and usually, there shouldn’t be big differences in the prices you see in the [https://store.ifixit.de|German Store] and the ones we have in the [https://www.ifixit.com/Store|US Store].
We’re trying to permanently control the prices and, if necessary, redesign. Set articles are usually always somewhat more favorable than the respective individual parts, but I totally agree with what you’re describing in the case that someone already has the tools.
The iPhone 7 doesn’t seem to be a single case, so we’re trying to find a better solution for all display kits and can unfortunately not do a quick fix for just this item right now. What we’re discussing is including the adhesive with the screens, similar to how we already do for iPhone batteries, but that change would need some time still.
Be assured that we’re very grateful for your reaching out to us and drawing our attention to this unintended discrepancy between pricing and mission. We’re working on it!
Thank you!
