I have started renovating my kitchen and a section where I pulled out cabinets did not have tiles underneath. This section of floor will be exposed when I'm finished so I need to insert 3 matching tiles, (which I can't buy anywhere). I am considering lifting some tiles from under the other cabinets to insert in the exposed area. Any suggestions on how to pry some tiles off the floor without breaking them so they can be re-used? The mix sticking them to the floor is quite sandy and not rock solid so I have hope.

Thanks in advance, Stuart.
