WOW & BC Client Purchases Needed?

Since I bought WoW over 2 years ago, and BC in jan this year, will I need 4 additional wow purchases and 4 BC purchases? Or does purchasing BC also give me wow?

Basically, whats the cheapest route to purchasing all the wow/bc clients?

You need to buy both, but WoW is pretty cheap these days, it's TBC that costs a bit more still

edit: use "invite a friend" though, you get 10 day trials, then use cheap upgrades to full WoW accounts and add TBC, you get a month free on your main box from it :)

You don't get the original WoW with TBC.

If you're not going to start either a Draenai or a Blood Elf, you can postpone buying TBC until your lot closes in on the mid-50's, when it's worth getting your team portaled over to Outland.

You can upgrade your account to TBC instantly, online, and since you already have the TBC disks you won't need to download the data when you make the decision.

WoW is $20 USD and BC is about $32 or so right now on Amazon, free shipping. Per account.

Cheapest entertainment out there IMHO.

Thanks much all!
