I'm hardcore anti-online shopping in our studio so here's what we do when the question pops up on long distance family orders. When asked we say "Since we're a professional portrait studio where the entire experience is done one on one and in-person, what most clients do is they just mail the DVD slideshow then their family can be apart of the experience. Then they can mail it back to you with money and what images they want you to order for them."
Ok so basically what this strategy is doing is #1 it's keeping everything offline. #2 It's an additional up-sell technique for our DVD Slideshows which are $75. If sitting there crying at the slideshow didn't sell them on it then this is another tactic that might. #3 they already said they were buying the DVD but they pop off with "Well there's no way I'm giving up my DVD they might see it and not send it back LOL .. can we order 2 copies?" Yes You Can.
and in cases where they might buy 2 copies but kinda debating back n forth over it I will consider what they have already spent. If they've only spent $500 then yeah they can just keep debating on it but if I've already made at least a grand off them I will say "tell you what I'll give you the second DVD for 50% off." ... good customer relations and I'm still profiting.
