A good price for this Lego 42100 Liebherr R9800 set. USD$339.99 works out to be about AUD$445 if using a credit card/debit card that doesn't charge any additional foreign exchange fees(ie. 28 Degrees, Citibank Plus, ING, Bankwest Platinum, etc..). Cheaper than paying Lego Australia's RRP of $750 for this Technic flagship set
Don't forget additional cashback from cashrewards. Works out to an extra discount of $9 or so.
Will be delivered from UK, so might take some time, depending how lucky you are. I've ordered from Zavvi(and also IWOOT, same parent company) and sometimes I get it the next week, others have been delayed a month or two. But I've always received my goods in the end.
no cashback for zavvi us
