Teambuy.ca has teamed up with Canadian company Jilly Bo Billy Boutique to offer you a deal. Spend $20 for $40 worth of online children's clothing and accessories at Jilly Bo Billy Boutique.
I found this deal through York Region on Teambuy. If you get directed to your own city just check out York Region and their side deals.
There is the usual fine print. There is a maximum of 1 voucher per person and maximum 1 voucher as a gift. Taxes are not included and shipping is not included. Shipping is very reasonable though, $6.95 per order or free shipping on orders of $100 or more.
This store specializes in offering you "past-season designer items, overstock, samples, and weekly deals" so you are already going to be saving on some really nice stuff.
Voucher expires 19th, June 2012. Deal expires in 4 1/2 days.
