yeah shipping is key that matter in this. Will be necessary to have sellers for each region, to lower the costs of delivery.

I will not order 100 TP from a seller delivering from US or China to Italy.

Buying from local stores is the best way. So for all these daily products we have to convince more local small shops to accept bitcoin. In my case was years and years of convincing work until I find 2-3 that can deliver to me anything I need and pay in BTC. So I sporadically buy online, only when I find something better or they cannot deliver in time.
