They were $19.99 including delivery, I was going to buy instore to save on postage but could not find them (generally $10 cheaper than online).
Noticed price drop to $9.97 last week, so ordered a pair. Quality looks alright, double wall construction with a rubber ring at the bottom to prevent slipping around.
Also available on eBay from a different seller for $13.81 delivered, but only 2 available at time of posting.
Love' Em Beef Liver Treats also looks good value, 2 x 500g packs $19.97 delivered. They are usually $20+ for 1 pack in pet shops. Reviews are very positive.

Looks pretty good quality and stable for the more robust doggie out there.
For our cats we generally buy a stack of China bowls from the op shop and throw them in the dishwasher. They, generally, cost a buck each.
