YOu got me very curious about this too. From what it says on their website under FAQ's, welcome points: "Points are valid for 12 months from the date issued. Points will not be reinstated or extended." birthday points: "Your $25 Birthday Reward will be automatically added onto your Landry's Select Club account on the first day of your birthday month. Birthday Rewards expire on the 15th of the month following your birthday month. Birthday Rewards can be deferred but will expire on the 15th if unused. If you register your account during the month of your birthday, your Birthday Reward will automatically be added to your account 24 hours after your account is registered. Regardless of sign-up date, the Birthday Reward will expire on the 15th of the following month" As far as using them together: "Rewards are redeemed in the order they were earned. Restaurants do not have the option of selecting which reward to redeem from a members account. The welcome reward will automatically be applied on the member's first visit to the restaurant following registration." I hope this helps !
