is there any plugin for this requirement ??
i want to give discount to users who are logging from specific ip address or ip addresses . let me clarify more specifically . if i want to give auto discount for all users of an specific ISP , the best way is users loging from a specific ip addresses that i declared will get that discount automatically when they submit their order.
is it possible ??
I didn't found anything like that at the https://marketplace.magento.com
I can imagine a way to, probably, solve the requirment but you will need some customization.
Maybe you can show a banner (at some place into the store) saying to use some Coupon to get a discount.
That part could be solved with a GeoIP module and some simple validation for a block.
Then, you should use an observer to detect when a customer enter a cupoun to the cart. If the IP is into the allowed list, you'll allow the coupon to be entered. If not, you can deny and show a message.
It needs a little bit of work, but I guess you'll get the feature.
(my 2 cents)
