Tiers

Does this plugin allow the following tier structure:
1-10 New Customer = 15%
11-20 New Customer = 20%
21-30 New Customer = 25%

up to $499 Repeat Customer = 10%
$500 – $999 Repeat Customer = 12%
$1000 – $1499 Repeat Customer = 15%

Both of these structures would need to be applied together.

Thanks,
Erv
