Hello Ashburton Imports,
I would try looking on eBay regularly - try searching for 'Baby Wholesale Lots'. Often eBay provides the best bargains, even with currency conversion and shipping.
Also try having a look at eBay stores specialising in baby gear, such as Link hidden: Login to view

Another idea is to contact the manufacturer directly of a baby product you like.
Whether you find a supplier on eBay or elsewhere, get ready to negotiate the shipping costs down to an acceptable level. You'll be surprised what a bit of bargaining can achieve! Good luck :)
