I bought with the original deal when each tier was $75 and had much different limits. Am I able to just buy more codes here and stack? And as such, will it just increase my existing limits by the number shown on the amount of codes? Or how would that work?

For example I have 4 codes activated previously and I paid for a special 1-time addon for daily polling which gave 400 keywords, 4 domains, 80 reports, 8 site audits. If I buy another 3 codes now which offer 4 domains, 225 keywords etc... will adding those increase my limits to 625 keywords, 8 domains, 160 reports, 16 audits...etc. while maintaining my daily polling? Or would it count as me having reached the current 7 code tier only increasing my limits by 125 keywords to a 525 total keyword count? Or would it be based on total cost to determine the limits - at a cost of $300 for 4 original codes + 3 current codes at $147 = $447 total cost which would technically put me at the current 10 code limit (actually overpaying by $6) that would provide a whopping 675 keywords, 12 domains...etc.?

Or am I just I ineligible to stack here? lol

Thanks for your insight on how this would work. Love the software! Easily falls into my top 3 AppSumo purchases of all time.
