You can find better deals online, actually. Penguin Magic has somewhat lower prices than most web shops and storefronts, even on some hard to find cards. Also, if you are after decks like Monarchs and similar, Barnes and Noble site often sends out 15% off (or even 20% off) coupons by e-mail allowing you to order most items, include card decks, at a discount. Amazon.com is often a hit or miss in that area, but their prices always fluctuate, and with a site like camelcamelcamel.com you can set up free "price alerts" that will notify you whenever any desired item gets its price lowered on Amazon; very useful.
