One product each size a different price

I am very new to zen cart and have been able to work my way around most things fairly easily.

One thing that I am having trouble working out though is if it is possible to achieve a different price on a per size basis for each product.

Example is that I will be listing canvas photographic prints once my store is set up. Each image has the potential to be purchased in a number of different canvas sizes, but obviously the price would vary depending on which size was selected.

A secondary issue would be that my prints will be in limited editions, meaning that no matter what size is purchased the overall stock level will drop until sold out.

A third issue (gee, ain't this fun :blink: ) is that alongside the canvas prints I MAY (not 100% decided yet) offer the ability to purchase a copy of the print as a greeting card, and there would be no stock limits on this type of print.

Just to make it all that much more confusing, canvas prints and greeting cards would obviously have different shipping rates. I have set a table for rates on the prints, and think I can easily incorporate a table for cards, but when an order may contain both types things get tricky, though I have not yet begun to venture into this part of the setup.

Hope somebody can point me in the right direction for the size/price thing at least.

Cheers

Update : I have found a solution to the pricing option part of the problem via the dynamic price updater by chrome.

You can easily account for differently-priced size options in the standard Zen Cart attributes system. You can either have the base size as the base price of the product, with larger sizes adding to the price, or set the product to "priced by attributes" and have each size listed with its full price. The product would then say "Starting at $x.xx".

For stock management, look at Kuroi's Stock by Attributes mod.

Thanks gjh42. I will have a look at that.
