Overall, a great purchasing experience.
I bought 2 MTG booster boxes and a preconstructed deck.
Their price for the booster boxes (current release) was about $5-$10 lower than most places (Amazon and others).
I was in no hurry to get the items so the option for free shipping (with minimum $100 purchase) was welcome.
I received an e-mail with UPS tracking number within 1 business day of the order so they got it out timely. It was packaged properly(in a reused medical products box; no problem as long it helps them keep prices low and make an acceptable profit) and arrived with no damage and factory sealed.
Their website was slightly difficult to browse for products because there wasn't an easy way to view all MTG stuff on one page. At least I didn't notice any way to do it and if there is an easy way to do it, then it's not easy to find.
Checkout process went well with no problems.
I didn't have a need to contact the seller so the customer service rating is based on the overall combination of price, free shipping & timely delivery.
