have TT's site up and be signed in.
once the sale starts, select "all" view and pick your choice. do one tip at a time. if you do multiple tips in the basket and someone else grabs the same tip, your whole cart will be booted when you try to check out.
when making your selection, DO NOT reload. it will just slow you down. servers are going to be busy so be patient while waiting for it to go to the next page.
anyway, good luck and most importantly, have fun!
