This issue is not one of BFG not being a very good site from which to purchase games, because it is. But rather a marketing ploy which isn't followed in the Real World(RW). No where in the RW, in any of the stores I shop at, am I given merchandise which I must re-shelve or be charged for when I reach the check out stand. No where at any of the stores I shop at does anyone try and put something into my cart, which I don't want, in the hopes I'll miss the item and have to pay for it when I check out.
When I shop online, and see boxes already checked, offering things I don't want, and I have to uncheck these boxes, it makes me wonder if that site is desperate to get people to buy that particular item or service. As with RW stores, it should be up to me, and me alone, to chose the products and/or services I wish to buy. No one on any site has the right to make that decision for me or hope I'll miss seeing that particular something that has been added to my order. If any site has a particular product or service they wish me to buy/try, then they should make sure they advertise it while I'm on that site. Otherwise, let me be the decision maker when it comes to my purchases.
If something gets your goat, it just proves you have a goat to get.
