I monitor my online credit card spending very carefully.....and today I noticed a purchase amount that didn't seem right...it was from amazon uk...and the amount wasn't familiar either....I have 2 upcoming pre orders(Tangerine Dream and King Crimson)but neither was for this amount and it was too early for them to ship it....they usually charge it around the time they ship it...so I contacted amazon UK via a chat session and the rep told me they are "trying" a new system for billing....so if you see a "pending" charge on your credit card and the amount isn't the price of the pre order...it's probably due to this new system...
