(Just a hypothetical. Not based on real facts yet, but might come up in the future.)
Suppose there is local game shop where I play from time to time. There is no entry fee for showing up to play. There might or might not be prize support, and if there is, it is the usual Fantasy Flight prize support (and not e.g. free packs, etc.).
The shop's prices are MSRP. So, a single ship is usually $15 an expansion. Bigger ships like the Falcon are $30 or more.
Now, online prices for some ships are less expensive than the prices at the store, sometimes up to 50% off if I buy online. (Shipping is not an issue, as the online shop I know does not charge shipping for orders over $35.) I do understand that the game shop has overhead, and I do want to support my local game shop especially since the shop already does not charge an entry fee for playing games there. However, if a particular ship is significantly cheaper online, I might want to buy those ships online instead of at the shop.
So, my question is, would it be considered rude if I play at the shop and make some, but not all, of my purchases there? Is there a rule of thumb for what percentage of my units should be purchased at the store vs. from some other source (e.g. online, Craigslist, etc.)? Has a venue ever given you a hard time, etc. because you brought figures, which you did not buy there, to play?
Now a twist: Suppose I go to two game shops to play, both on an occasional basis (maybe 2-3 times a month). How should I divide my support between the shops? Is there an unspoken expectation that if I play at a shop, that I would necessarily make purchases there?
[Note: The sole purpose of this question is just to inquire into X-Wing commonly accepted etiquette as it pertains to dealings with game shops.]
