Help Needed in Subscription

I had been member of this blog and also had a Jr. VIP Membership (as I was donor), as my subscription finished now I want to renew it, but I am just confused whats the difference between the following two.

Jr. VIP Membership
Premium Membership

Also is there any chance we get any discount from BHW on Xmas or New year in subscription.

Thanks

donor allows u a bigger inbox and links in your sig which a normal member can not
vip pretty much same cept u get a larger inbox and can apply for sales threads
just get VIP there same price
