tektek is cool cause it lets you tryon items to see if you want it before you buy it!!!! its prettynice.
Also the Sealed Envelope 10/2008 will may be opened on the 8th of this month (i believe 3pm its usally the time). Im not sure if its better to get one now or wait, gaia econ is being a little screwie as of latly. Really the price of MC depends on the demand of it (and how old it is :P )
