Can We Take a Picture?

Does anyone else have a child who spots a toy while out and just has to have it?  

We usually try to nip this before it starts, and when we unbuckle and approach the store.

Passerby's can hear me saying,

'Today we are not buying toys.  You may look, but you may not ask to buy anything.'

'Yes, mama.'

Sometimes, I forgot.  

We get into the store and pass by the toys, and O jumps on the opportunity.

'Mama, today you didn't say no toys, can we some today?  PLEASE?'

What to do, what to do?

'O, we currently live in a hotel.  We just do not have room for stuffed animals.  You have as many toys as you need.  Would you like me to take a picture with you and the toys?  Then you can say goodbye to them.'

So far, this method has worked really well.  No whining, no complaining, and no tantrums.  What do you do when your kids ask for toys?
