Nice to see ZebPay is coming out with a sig campaign. But, why only newbie & Sr. Member? What about Jr. Member, Member, Full Member, Hero Member & Legendary? Also, you can have some special rates for Staff Members. 
Thanks for appreciating our effort. This is our very first campaign so it's important for us that it is manageable.
We'll plan for more exciting campaigns and for all members once we are done with this primitive one.
Regards.
