Need help finding stonemarket sahara slabs - Old dimensions, uncalibrated indian sand

[Left handed]

Hello, first post so fingers crossed someone can help.

Approx two years ago I bought a crate of stonemarket sahara Indian sandstone.

The slabs still havent been laid but to complete my project I'm going to need more slabs.

Now the problem. Went back to builders merchant who sold me them and found out stonemarmet changed the sizes, so, the new sized slabs won't fit in with the old sized slabs.

My OLD sized slabs are:

900x600
600x600
600x295
295x295
600x450.

The builders merchant rang stonemarket who said they had some and could sell them for £462/£23m2.
Think I got original slabs for no more than £300 so its a big price hike as I could buy the new sized slabs for £339 project pack and they're calibrated unlike the old style ones.

I have emailed stonemarket direct, this afternoon so waiting on reply.

Any advice or info most welcome.

£300 for how many metres LH? TBH I would just be glad they still have them and pay the extra
short term pain ,long term gain
