>>8668935>>8668935HLJ is decent but its mainly recent stuff and shipping from Japan will be costly. Your best bet is to order from there and let it accumulate for a few months then ship it all in one package to save money. Another onus is that they backorder moncolle so even if its not currently in stock then can order it and it will, likely, come in eventually.
You can also try using Mandarake for older figures but again, if you're importing its best to buy in bulk so maybe make a list of what you like before you go searching. With Mandarake you're also ordering from individual stores so make sure when you do a multiple item order they're all on the same store, otherwise you'll naturally have to pay to ship from two separate ones.
buying these individually from US stores will run the cost up because they tack the cost of importing on the figure. Sirfetched for example is a $4 toy in Japan.
