i looked for this jalpur brand too recently. none of the larger places had it or had heard of it.
i did manage to find a few boxes in some smaller shops in blackburn,(achari masala and some others, i forget which) no garam masala though and the ones that were on the shelf were dusty and out of date! :

i bought some natco gm to try
revolting flavour if you ask me, its going straight in the bin
