Lynn, I run the technology department at Staples across from chinook center, and we sell sirus satellite raido which seems to me to be the best (I thought I heard something about XM beeing bought out by Sirus) And we do sell the boom box that u can place the reciver in and thus making it portable. I also belive we have the portable unit that is also kind of like a ipod!
Anyways come stop by ask for Brad, that of course is me and I would be happy to sell you one, lol.
Btw, getting the lifetime membership I think is around $500 but its well worth it, cause you do not have to pay a monthly subscription.
Oh also before I forget, you see it cheeper anywhere else all I need to do is varifie the price and I will match it, and then knock off 10% of the diffrent on the price (Usally not that much but still makes us lower then anyone else!)
