Can some one help me to fix this?

Your in luck if you find this popular T-shirt design on sale now because It is sold as a limited edition item and isn't available for re-stock. It's rare so, buy it fast before it goes/before it's gone forever/get it/grab one fastbefore it's too late/before they're all sold. Thanks

Tiff deeThis kind of design(T-shirt) are very rare to find, limited to one patch, we wouldn't re-stock again after this patch, grab it fast before too late.

This design is very rare, limited to one batch. We won't re-stock after this batch, so grab it fast before it's too late.
