LIGHT LABS is pleased to offer CELLTREAT's April 2026 promotion — one of the best lab supply deals of the spring. Buy any 3 cases of CELLTREAT products and choose your reward: a free case of product OR a free insulated lunch bag. Mix and match your free items as you go — the more you buy, the more you earn.
This promotion is valid for orders placed between March 30, 2026 and April 24, 2026, for end-user customers in the contiguous United States only. Promotion submission forms must be received by May 15, 2026.
How the CELLTREAT April 2026 Promotion Works
The promotion is straightforward — every 3 cases you purchase earns you 1 free item. The more cases you order, the more free items you can claim, up to a maximum of 4 items per lab:
- 3 cases = 1 free item (free case or free lunch bag)
- 6 cases = 2 free items
- 9 cases = 3 free items
- 10 cases = 4 free items
And the best part — you can mix and match your free items freely. For example, if you purchase 6 cases, you could choose 2 free cases, 2 lunch bags, or 1 of each. The choice is yours.
