So my DH has started looking for better pricing for me for selling cakes and a co-worker of his told him about this 'country store' in Tillsonburg Ontario (Near London). I don't know if they deliver, however, I am sure they would if you asked!
One of the prices they gave him was for white rolled fondant. They were:
650 grams (roughly 1.5lbs) for $5.95 or 5 kg pail (11 lbs) for $35.99.
Here is their website, unfortunately they don't list products on it, but you can email them and they respond quite promptly to inquire. It is a family run business. Hopefully this will help.
DH and I are planning a trip one day soon to see everything and get more prices.
Thanks for that link! We go to London a few times a year, so maybe I'll stop in there next time.
