Actually you will receive it within the next 7 days to me means get it within 7 days.
But "These units ship within 7 days." isn't really open to interpretation, but if it was then personally I would have contacted the sales and asked for confirmation of the meaning, instead of stressing over it.
You're looking at a different page. I'm talking about under "Where to buy", on the main site.
I don't know if I recently entered some sort parallel universe, but the world I use to live in, the vast majority of fluent English speakers knew what the phrase "delivered to you" means. Something is only delivered once it arrives at it destination. The issue isn't that the text is unclear or ambiguous, it's just inaccurate, that's why it should be changed.
