Shopify extension to show Rollo's shipping prices on store

I think it’ll be very beneficial for people using the Rollo App for Shopify websites & want to charge customers for the freight, there should be a way to make customers that visit the Shopify website to see freight quotes before they checkout.

For time being we’re using the UPS Small Package Quotes App but we need to enter the discount percentage amount that we get for each shipping option (UPS Ground, UPS Next Day Air, etc.) so the app can show correct prices.

Meanwhile, can you please post the exact UPS discount percentage you offer for each shipping option?

Thanks
