Amazon UK has deep savings for both LEGO City Space Port (60080) & LEGO City Deep Sea Exploration Vessel (60095) at £55 each. That comes out to about $82 shipped which is 31% off the retail US price. Both are good deals for recently released sets.
Importing sets from Amazon UK is pretty simple since the login is the same as your regular Amazon account. Use the currency convertor during checkout and it’ll convert the price from British pounds into US dollars. Buying both sets will make them cheaper since you save on shipping.
