I, for one, have held off making the final portion for our group entry display. The rest is built and we designed it to be reusable for the foreseeable future.
An item that is around $200 that may or may not be used this year (the durability of these things in storage is a potential issue) is a factor in our chapter's planning.
There are two local chapters here, and one has already decided against sending that group's display entry as their chapter leadership has opted out of attendance for health reasons (the doctor said NO!) but it will hold for a year. I just might enter my contribution and see how it fares.
For others, there is the consideration of time off work, travel arrangements (especially airfare) and other cost factors that might not be so easy to recoup at the last minute. Last-minute cancellation fees are not always consumer freindly.
