As an international Logos user whose savings are denominated in British Pounds (GBP) rather than US Dollars (USD), I have a suggestion. One of the major selling points of pre-pub items is that once you've placed your order, the price you pay is "locked in". But this only applies to the USD price.
Once a pre-pub item has acquired sufficient interest to go "Under Development", it would be helpful if Logos could accept payment at that point. This would allow Logos to receive positive cashflow up front during development while allowing me as an international customer to lock in the current GBP/USD rate.
This would be especially beneficial when customers suspect that their domestic currency is about to drop in value against the USD, an event which pushes up non-USD prices for overseas customers (sometimes dramatically so in a matter of days or weeks) while bringing no additional financial benefit at all to Logos.
As a former computer programmer myself, I doubt that much development work would be needed to create such a facility, and I for one would appreciate it very much in these cost-conscious times.
