Today I will write about a company that has made its way through the gaming community in the past 3-4 months - Strictly Broken TCG or SBT.
Strictly Broken is a UK based online retailer of Magic: The Gathering, Yu-Gi-Oh! cards and others TCGs with focus on 'sealed booster' formats. They are offering blind preordered prerelease packs for MTG - mostly for Standard environment sets (beginning with Battle For Zendikar) which you don't even know what cards are inside when opening it. You can instead choose to buy all other MTG products in 'singles' format in case you want to pick specific cards in need for your decks.
Their prices are similar to the ones of MTGStocks for regular paper magic cards.
I've found out about this company on MTGSalvation forums after browsing the latest spoilers for Battle For Zendikar. Right away I was interested in their product since I play standard decks and like the idea of blind prerelease packs which you can't get anywhere else (for example, not even at WOTC events). So I browsed their website where I saw that they offer sealed booster boxes too - one of them (Standard Box) was pretty much on par with the prices stated by TCGPlayer's marketplace (which means this is very often higher than MSRP), so instead I had to go with preorder pack option.
I decided to get two preorder packs of BfZ. When you're buying this way, you can choose when do you want to receive your order (Week 1 or 2), which means that there is a chance for the product be spoiled before it gets to you. I couldn't avoid some spoilers on internet and in game stores too during this time, but at least I had the option of getting my cards (or money back) immediately if Wizards spoils something huge that will make them obsolete.
Magic: The Gathering players in the US who want to try out prerelease packs should think about the risks of buying these blind. If you're willing to take that risk, SBT is a great option for sealed booster boxes and singles (and they offer free shipping). It's important to keep in mind that this company operates outside of the US though - which means there are some additional steps involved when it comes time for delivery.
